Reenable tests with mongoid on Rails 5 and up

Devise hasn't been tested with Mongoid since Rails version 5, only 4.x
was still running those tests.

This enables the tests again on all currently supported Rails versions,
with their respective mongoid supported versions. There were a couple of
minor tweaks to make it happen, namely:

* The way we were dropping the session before doesn't work in later
  versions so I changed back to calling `purge!` which appears to
  work fine. We used to call `Mongoid.purge!` but that changed in #4686.
* Some of the configs in the Rails test app were setting Active Record
  values when outside of the AR ORM tests, updated those to make sure
  they are not set when running mongoid ORM tests.
* The validations added to the shared admin code in tests were only
  checking for Rails version 5.1, but we need to use the same check for
  AR 5.1 that is used in code, otherwise it will try to use methods not
  available in mongoid there.

I also had to lock the sqlite3 gem on Rails 6 versions to 1.5.x, due to
it dropping support to Ruby 2.6 on v1.6+ now, and those Rails 6 versions
need to support that Ruby version.

Finally, I locked mongoid to v7.5+ but not allowing v8+ yet, there seems
to be some change to dirty attributes that I need to look into which is
making a handful of tests fail. For now, this should hopefully get us to
green as step 1.
