Prevent updating timestamp cache more than once for the same space

Description

Right now, when the timestamp cache is updated it does not account for multiple updates to the same space. This causes multiple unnecessary writes to the second level cache. We have a case where there are ~20 inserts and each causes a timestamp cache put even though the value is the same.

Ideally PreInvalidate(object[] spaces) and Invalidate(object[] spaces) should be changed to accept ISet<string> like IsUpToDate(), but that would be a breaking change.

FWIW, this may or may not be considered a bug and also affects NH since this was introduce around 2005.
