Ref Bot does not take correct project branch into account

See e.g. https://gitlab.cern.ch/lhcb-rta/reference-update-bot/-/jobs/38694054

Issue appears to be the Ref Bot thinks Boole should have a 2024-patches branch, whereas even in the 2024-patches build uses Boole uses master.

Ref Bot should correct take this into account.
