Fix not reseting filter_matches corrupt pulse height results

[GuySten]

Description

When pulse height tallies were tallied when the FilterBinIter was empty the particle filter_matches were not reset correctly.
That fact corrupted the tally results.
This PR fix that behavior and add a unit test that failed before.

Fixes #4018
