Errors on rails 4.2.3

[dazza-codes]

.gemspec is pinned to rails 4.2.2 (actually just actionpack 4.2.2 is the issue), because errors arise in 4.2.3, i.e.

1) Triannon::AnnotationsController#create creates a new annotation from the body of the request
     Failure/Error: post :create, ttl_data, anno_root: @root_container
     NoMethodError:
       undefined method `_run_save_callbacks' for #<Triannon::Annotation:0x0000000b00b5d0>
     # ./app/models/triannon/annotation.rb:43:in `save'
     # ./app/controllers/triannon/annotations_controller.rb:84:in `create'
     # /home/travis/.rvm/gems/ruby-2.2.2/gems/actionpack-4.2.3/lib/action_controller/metal/implicit_render.rb:4:in `send_action'

Note that fixing the rails gem to 4.2.2 in .gemset did not fix the travis builds, so it's not entirely clear that 4.2.2 vs. 4.2.3 is the source of the problems that motivated this issue in the first place.

The Annotation class might need to be updated for rails 4.2.3, see

This might be fixed by https://github.com/sul-dlss/triannon/commit/407f85c89259b71a814ea329f6d5369f71213d0d

The fixes have passed a build in travis, so closing this issue as fixed (mucho fixed).
