Invalidate binary search bounds consistently.
_bt_check_unique() failed to invalidate binary search bounds in the
event of a live conflict following commit e5adcb78. This resulted in
problems after waiting for the conflicting xact to commit or abort. The
subsequent call to _bt_check_unique() would restore the initial binary
search bounds, rather than starting a new search. Fix by explicitly
invalidating bounds when it becomes clear that there is a live conflict
that insertion will have to wait to resolve.
Ashutosh Sharma, with a few additional tweaks by me.
