t0000-basic: Add ls-tree recursive test back.

When we updated ls-tree recursive output to omit the tree nodes,
246cc52f38 adjusted the old test
so that we do not expect to see trees in its output.  Later,
with 0f8f45cb4a, we added back the
ability to show both with -t option, but we forgot to update the
test as well.
