rebase: fix fork-point with zero arguments

When no arguments are specified, $switch_to is empty so we end up
passing the empty string to "git merge-base --fork-point", which causes
an error.  git-rebase carries on at this point, but in fact we have
failed to apply the fork-point operation.

It turns out that the test in t3400 that was meant to test this didn't
actually need the fork-point behaviour, so enhance it to make sure that
the fork-point is applied correctly.  The modified test fails without
the change to git-rebase.sh in this patch.
