Problem/Motivation
Language module alters configuration during module installation (code>language_modules_installed()). Language module shouldn't touch existing config if the modules are installed during config sync.
Proposed resolution
If we are syncing config, we need to assume the config is right and don't perform any "purging".
Remaining tasks
Patch with tests.
Test should install a profile with language types configuration (negotiation), and verify it's not altered.
User interface changes
None.
API changes

Data model changes
