vim-patch:8.2.2465: using freed memory in :psearch

Browse Source 
Problem:    Using freed memory in :psearch. (houyunsong)
Solution:   Check the current window is still valid.  Fix flaky test.

Test_cursorhold_insert timer's 100ms delay was already LoadAdjusted, but change
to 200ms (still LoadAdjust) to match Vim anyway.
