test: testCheckCompatibility fixes for Bedework

Two bugs introduced in 632d529 caused testCheckCompatibility to run
for ~8 minutes on servers with a search-cache delay (e.g. Bedework).

Also cleaned out redundant entries from the bedework compatibility matrix,
and added `save-load.event.recurrences.exception` as broken (hm, why
did this pop up just now?)

prompts:
claude-sonnet-4-6: why is `pytest --last-failed` just hanging now?
(I also tried asking how those duplicate lines got there in the first place)
claude-sonnet-4-6: Skip doing more research, just delete those two lines
claude-sonnet-4-6: `pytest --last-failed` still seems to hang.
claude-sonnet-4-6: this problem has only been manifesting itself lately.  What change caused it?
