Stop using mocha on app_rails_loader_test

Stop requiring mocha automatically

We are planning to remove mocha from our test suite because of
performance problems. To make this possible we should stop require mocha
on ActionSupport::TestCase.

This should not affect applications since users still need to add mocha
to Gemfile and this already load mocha.

Added FIXME notes to place that still need mocha removal
Merge branch 'rm-remove-mocha'
