Upgraded the Acts As Taggable gem
Created by: jvanbaarsen
What does this MR do? It upgrades the acts-as-taggable gem
Why is this MR needed? It removes the patch from the initialisers, it also adds some possible hooks for speed improvements (tags#taggings_count). But I think the important part is the removal of the acts_as_taggable_patch.rb
Does the reviewer have to watch for something? Yeah, please wait for the tests to finish. Didn't run the full suite locally.
