Cleanup: Remove an unnecessary AutocompleteMatch& calculation from
OmniboxEditModel::OpenMatch().

I traced the origin of this weird code back to the days before OpenMatch() took
an AutocompleteMatch; back then, we constructed one so we could get at fields
like |fill_into_edit| that weren't provided to OpenMatch().  Now that we pass
this in, I believe the calculated match should always match the passed-in match.
