Don't reload factory definitions in test_helper

They will already have been loaded since the factories are now part of
the gem packaging, not just for testing the gem.
Load factories only from custom factories dir

Instead of reloading all factories with a new search path location
appended, FactoryGirl docs suggest loading definitions with ONLY the new
search path you wish to add. When the gem is reloaded later, this
configuration will be reset anyways.
