terminal: cursor back should not reduce by one with pending wrap

Browse Source 
Fixes #1183

I'm not sure why the original logic was there. When I translated the
original test cases to shell and ran them in xterm, they did NOT match
what Ghostty expected. This updates the tests to match xterm and removes
this case. We can add back in more tests if/when we figure out under
what scenario this original logic was correct (if it ever was).
