Clear CurrentResourceOwner earlier in CommitTransaction.

Browse Source 
Alexander reported a crash with repeated create + drop database, after
the ResourceOwner rewrite (commit b8bff07daa). That was fixed by the
previous commit, but it nevertheless seems like a good idea clear
CurrentResourceOwner earlier, because you're not supposed to use it
for anything after we start releasing it.
