Small fixes for problems found a few months ago during the testing with "reco without event building".
I took them out as !1145 (closed) will probably never reach a state where it is merged (at least not on my radar).
They should help with the following two cases:
Bmon
TRD2D but without TRD1D
=> The fix for the TRD1D/TRD2D case is only applied to the reco macro used in the CI, feel free to propagate it to the other mcbm2022 reco macros (I do not maintain them)
Probably of interest to: @se.gorbunov @a.bercuci @n.herrmann
