Move api error handling and timeouts to parent class

Fixes #4861

Since the around_action is defined before authorize_resource is called,
the handler needs to pass on the CanCan::AccessDenied exception.

I've added the timeouts where I think they were missing (e.g. UserPreferencesController)
but I've kept the exception for changeset#upload and traces#create
