Added another peak search reference

Re #9221. Corrected system tests
Adjusted PoldiPeakSearch systemtest

New intensity and background estimations lead to different intensity guesses,
so they are not comparable anymore.

In combination with new background estimation, some small peaks (which usually are no peaks) will not be found,
or different ones will be discovered.
