udebug: Always show tidCounter

udebug: Always show tidCounter

If the queried site doesn't have an active write transaction,
currently udebug doesn't show the tidCounter. The tidCounter can still
be useful to know (especially since some sites will become buggy when
tidCounter rolls over), so always show it.

This adds the "The last trans I handled was" message to udebug.
