IDLE: Fix test_debugger bug and buildbot failures (#112258)

Missing "requires('gui')" causes Tk() to fail when no gui.
This caused CI Hypothesis test to fail, but I did not understand
the its error message. Then buildbots failed.

IdbTest failed on draft Bdb replacement because so different.
Simplified version works on old and new.
