Fix CA merging issue in Jets, MinBias and improved CA Cache
This MR contains two fixes,
- removed AccumlatorCache decorator from functions returning MenuSequenceCA (Jets, MinBias)
- improvement of AccumlatorCache cleanup functionality to also handle the case when a collection of things is cached
Tagging @fpastore - I have seen only issue with muons and TLA which will be gone with !62136 (merged)
@khoo - for jets
@fwinkl - to have a look at the __del__
implementation
