t3432: test for --no-ff's interaction with fast-forward

Browse Source 
Add more stress tests for the can_fast_forward() case in
rebase.c. These tests are getting rather verbose, but now we can see
under --ff and --no-ff whether we skip work, or whether we're forced
to run the rebase.

These tests aren't supposed to endorse the status quo, just test for
what we're currently doing.
