adding taus to the full_menu_build test

This MR is an attempt to add taus to the full_menu_build. There are no errors, which was the reason to take them out in the first place. However, I see unexpected change of counts in muon chain: HLT_mu6noL1_L1MU6 . Since we have slice standalone tests I attempted to compare the counts among them and the full_menu test. For tau only test (updated reference) the counts of chains are the same as in full_menu_test. Muons are hard to guess as the number of events processed is different. Can we harmonise this? @rbielski ?

Tagging @sshaw @carquin BTW. I see menu is being filled with tau triggers. We should be running them in all possible tests.
