  1. Fix performance issues with checkAckFloor. 

    Bail early if new consumer, meaning stream sequence floor is 0.
Decide which linear space to scan.
Do no work if no pending and we just need to adjust which we do at the end.

Also realized some tests were named wrong and were not being run, or were in wrong file.
