Create from Bandersnatch Remotes are filling in fields incorrectly
The prereleases field for a Python remote is the opposite of the prereleases field specified in the Bandersnatch config file. Setting prereleases True for Python remotes includes prereleases while setting the field in the Bandersnatch config filters out prereleases. This logic should be switch to better match Bandersnatch's behaviour.
Also, Bandersnatch has now changed the names of their includes/excludes filters from 'whitelist/blacklist' to 'allowlist/blocklist'. This should be updated in the create_frombandersnatch viewset.
