This has no actual changes to Devise itself, just fixes the failing
tests when running against Mongoid 3 instead of Mongoid 2.
Mocha has been locked at 0.10.0 since 0.12.0 raises an error when trying
to set an expectation on a frozen object.
Tests were updated to work with both AR and Mongoid, some cases the XML
serialization was slightly different but both were outputting correct
and valid XML, and the id/_id field mismatch is now handled.
An active field was missing from the test models for Mongoid, and the
invalid :null => true options in field were removed.
- attr_accessible not set for test user model, making Serializable tests
inaccurate
- Mongoid does not `include_root_in_json` by default, so enable this for
consistency with AR tests
- Mark tests pending for Mongoid < 2.1 that fail there due to known bugs
- Add `:mongoid` key for i18n model labels
- Remove outdated shim of `update_attribute` that caused mass assignment
security to be applied (ugh, that took awhile to find)
