[1.3.X] Reverted [14563] because it introduced a dependency from core on a
contrib app (contenttypes). Fixes #16283, Refs #3055. Thanks TheRoSS for
the report and Aymeric Augustin for finding the problem.
This caused models shipped with some contrib apps to pollute the namespace
when user's apps had the same name (e.g. auth, sites), even when these
contrib apps weren't installed.
This undesired loading of contrib apps happened when model validation was
executed, for example when running management commands that set or inherit
`requires_model_validation=True`:
cleanup, dumpdata, flush, loaddata, reset, runfcgi, sql, sqlall, sqlclear,
sqlcustom, sqlflush, sqlindexes, sqlinitialdata, sqlreset,
sqlsequencereset, syncdb, createsuperusers, ping_google, collectstatic,
findstatic.
This could also cause hard to diagnose problems e.g. when performing
reverse URL resolving.
Backport of [16493] from trunk.
