Delete this test, it's quite broken.

This tests to see if your installed RT has the relevant callbacks, but
it can't possibly work on modern RTs (in fact I doubt it worked properly
on 3.8 since it never looked in plugins for the RTIR files).  It also
hardcoded a bunch of /opt/rt3 paths despite having support for knowing
RT's real installed path in other tests.

It also doesn't understand that autohandler callbacks moved to lib/ in
later 3.8s.

The utility in fixing this greatly outweighs the utility in having the
test.
Turn these into author tests
Stop doing things manually

Trust the test files to load RT::Test appropriately.
Use helper functions to find eht ticket create page.
Don't load the config again, clobbering RT::Test.
remove unused code
Switch to modern RT::Test framwork

Let RT load the extension and start the webserver.
Keep the no-plan part of the old tests.
Sleep otherwise when the autolock is cleared, it'll look like Duration is 0

Duration 0 causes the message to not be printed to the screen.  There's
a bug here around undef of course.
Match the newer message we get

Improve the debug message from running tests also.
This gets tested by RT::Test
Ignore tmp files from author tests
