Use test-lib.sh's `test_count`, instead instead of having
t7900-subtree.sh do its own book-keeping with `subtree_test_count` that
has to be explicitly incremented by calling `next_test`.

This just retains an existing pattern and all that, but I think this
pattern of testing makes for hard to read & maintain tests. It looks
like all of these could just be:

    test_when_finished "rm -rf repo" &&
    git init repo &&
    [...]

I.e. the only thing that's being done here is to piggy-back on the test
count to create a unique repo.
