Updating dependencies to desired versions.
Minimal changes to make tests runnable.

Although all tests fail they at least run now.
Gem database_cleaner was outdated.

Require BSON so it is available for use.

This was caught from select field test, maybe this is not the place to
require it...
Fixing has_many order_by, although test may be outdate.

Although test doesn't pass it may be outdated or biased.
