Fix nightly rt and automotive merging

The nightly rt merging cronjob immediately failed the second night because I forgot to push the intermediary branch rt-automated-devel. So when it got rebuilt the next night from scratch it got merged into rt-devel and automotive-devel in a way that required those branches to be forced pushed. Not good for development.

The easy way is to push that branch but that requires re-pushing rt-devel and automotive-devel. Not hard. Instead I wanted to remove that intermediary branch leaving less complicated logic and rely on an octopus merge. Should work better now and simpler to read.
