Fix cleanup setups

• Fix TOF geometry in mCBM 2019 03 setup by reverting to the right tag value (wrongly changed in !74 (merged), probably by mistake)
• Remove outdated setups for rejected "CBM with SIS18 beams" project

Fixes some problems brought to light by computing/cbmroot!1195 (merged), needed to be able to merge it

Of interest to @e.clerkin @v.friese @f.uhlig
