Allow SelectionCA merge with upSequences
- there are cases in which a menu sequence contains other sequences running before the InputMaker. This MR allow ?Selection/Ca to accept those when merging the reco code (mergeReco). This wa mergeReco() can be called only once, otherwise raises error: I think this is what we want.
- Side change one tau code that run mergeReco twice, causing crash.
- lowered warning -> debug for few CA-migration messages to reduce message redundancy
