Subject: [PATCH 1/3] [lldb] Improve completion tests
* Assert no completions for tests that should not find completions.
* Remove regex mode from complete_from_to, which was unused.
This exposed bugs in 2 of the tests, target stop-hook and
process unload. These were fixed in previous commits but
couldn't be tested properly until this patch.
