Use update_columns to by_pass all the dirty code on active_record

We think this is valid because we’re just storing new data that always will be valid

# #save or #update_attributes providing changes on serialized attributes do a lot of
# serialization and deserialization calls resulting in bad performance.
# Using #update_columns solves the problem with just one YAML.dump per serialized attribute that we provide.
# As a tradeoff we need to reload the current instance to properly manage time objects on those serialized
# attributes. So to keep the same behaviour as the attribute assignment we reload the instance.
# The difference is in the usage of
# #write_attribute= (#update_attributes) and #raw_write_attribute= (#update_columns)
# Ex:
# new_attributes[:st_commits].first.slice(:committed_date)
# => {:committed_date=>2014-02-27 11:01:38 +0200}
# YAML.load(YAML.dump(new_attributes[:st_commits].first.slice(:committed_date)))
# => {:committed_date=>2014-02-27 10:01:38 +0100}
