lib/repo: Do account for size with prune --no-prune

Browse Source 
I think this got changed in a refactor.  We definitely want
to total up the amount of space that *would* be freed even
with `--no-prune` AKA `OSTREE_REPO_PRUNE_FLAGS_NO_PRUNE`.

It's actually a bit terrifying this is apparently the first test case for
the `--no-prune` option...

Closes: https://github.com/ostreedev/ostree/issues/1480

Closes: #1483
