Title: When checking for conflicts using the history module, we should build the list of conflicting slugs from the history

…not the current values for those models, which may have changed.

NOTE: Rather than the changes to last_in_sequence, it’s possible to just change the FriendlyId::Slug#to_param to return the param rather than the id. But we didn’t want to change the public API for that model.

Addresses Issue #230.
