Title: Clear the AR column from remove_#{column}! (Issue #401)

Clear the serialization column by calling `remove=` and `write_identifier` on the mounter after the default behaviour has run.

@bcardarella also included specs for the case where the serialization column is manually wiped by the user, but I'm not sure I agree that CW should handle this (except perhaps by raising an exception).

See https://github.com/bcardarella/carrierwave-failure/blob/master/spec/carrierwave_spec.rb (line 35) and let me know what you think.
