Before this commit, when adding a tag on record and then
scheduling an activity, the tag was removed from the record.
This happens because reloading the chatter does not save changes.
Although there is a `keepChanges: true` option, this looks
ineffective. This commit fixes the issue by letting chatter reload
always save any changes.
