Description

Description of problem:
Pulp will returns wrong 'pkglist' if an erratum exists in multiple repositories and user syncs multiple of these repositories

For example:
Erratum 'RHSA-2019:1235' exists in both 'rhel-7-server-rpms' repo and 'rhel-7-server-optional-debug-rpms' repo with the following 'pkglist' respectively

rhel-7-server-rpms:
"ruby-libs-2.0.0.648-35.el7_6.x86_64.rpm",
"ruby-libs-2.0.0.648-35.el7_6.i686.rpm",
"ruby-2.0.0.648-35.el7_6.x86_64.rpm",
"rubygem-bigdecimal-1.2.0-35.el7_6.x86_64.rpm",
"rubygem-psych-2.0.0-35.el7_6.x86_64.rpm",
"rubygem-rdoc-4.0.0-35.el7_6.noarch.rpm",
"ruby-irb-2.0.0.648-35.el7_6.noarch.rpm",
"rubygem-io-console-0.4.2-35.el7_6.x86_64.rpm",
"rubygems-2.0.14.1-35.el7_6.noarch.rpm",
"rubygem-json-1.7.7-35.el7_6.x86_64.rpm"

rhel-7-server-optional-debug-rpms:
"ruby-debuginfo-2.0.0.648-35.el7_6.x86_64.rpm",

After syncing these 2 repos to the Satellite, Pulp will only list the 'ruby-debuginfo rpm' in the erratum 'pkglist'. Pulp will calculate the wrong applicability for the consumer because the erratum is listing only 1 rpm.

Test in "foreman-rake console":

Before enabling debug repo, the erratum shows 10 packages:
pp Katello::pulp_server.resources.repository.unit_search("046aa6b4-6369-4ef7-a3f7-3959250bd86f", {:type_ids => ['erratum'], filters: {unit: {"errata_id": "RHSA-2019:1235"}}})[0]['metadata']['pkglist'][0]['packages'].size
10

After enabling and sync debug repo. the erratum shows only 1 package.
pp Katello::pulp_server.resources.repository.unit_search("046aa6b4-6369-4ef7-a3f7-3959250bd86f", {:type_ids => ['erratum'], filters: {unit: {"errata_id": "RHSA-2019:1235"}}})[0]['metadata']['pkglist'][0]['packages'].size
1

pp Katello::pulp_server.resources.repository.unit_search("046aa6b4-6369-4ef7-a3f7-3959250bd86f", {:type_ids => ['erratum'], filters: {unit: {"errata_id": "RHSA-2019:1235"}}})[0]['metadata']['pkglist'][0]['packages'][0]['filename']
"ruby-debuginfo-2.0.0.648-35.el7_6.x86_64.rpm"

exit

Steps to Reproduce:
1. Ensure you have a RHEL 7 client with older ruby version. Lets say Client 'A'.
2. Enable and sync 'rhel-7-server-rpms' repo
3. Go to Web UI -> Hosts -> Content Hosts -> Client 'A' -> Errata tab -> Filter "id = RHSA-2019:1235" should show this erratum is applicable/installable.
4. Enable and sync 'rhel-7-server-optional-debug-rpms' repo
5. Now need to do something so that we can FORCE recalculate the applicability for Client 'A'

On client 'A' do:
subscription-manager repos --enable="rhel-7-server-optional-debug-rpms"
katello-enabled-repos-upload -f

6. Wait for the regenerate applicability task to finish
7. Go to Web UI -> Hosts -> Content Hosts -> Client 'A' -> Errata tab -> Filter "id = RHSA-2019:1235" shows empty result.

Actual results:
Errata RHSA-2019:1235 is not applicable to Client A

Expected results:
Errata RHSA-2019:1235 is applicable to the Client A

I think we need to do "$unwind" twice to flatten the array list. I made the following change and test. It seems to fix the issue.
