Update frontend canonical-rails dependency
Update frontend canonical-rails dependency

Version 0.1.0 of canonical-rails introduces Rails 5 support which is
needed for this branch.

I tried to resolve the dependency issues with as few changes as
possbile, although more are possible. Such as an update from Rails5.rc
to Rails 5 stable and rspec-* from master to 3.5.0 which has Rails 5
support.
