Remove HI legacy menu sequence definition

This is just minor cleanup of HI menu. Testing was a bit challenging though as HI tests fails and I had to turn off egamma. In addition I have made a following modification to one of test to increase execution "probability" and realy see events passed by chains:

@asmaga @kciesla - you may consider such change to make test more relevant.
