builtin-branch: fix -v for --[no-]merged

After the optimization to --[no-]merged logic, the calculation of the
width of the longest refname to be shown might become inaccurate (since
the matching against merge_filter is performed after adding refs to
ref_list). This patch forces a recalculation of maxwidth when it might
be needed.
