[3.1.5] Restore 3.1 handling for admin_channels, admin_roles (#6770)

Omitting default collection admin_channels, admin_roles on a PUT /db/_user should not remove those channels - callers must explicitly specify an empty array.

Handling for named collections is unchanged - if scopes/collection is specified in collection_access, contents are treated as a replace.

Added tests for interaction with JWT channel updates.
