MDBF-1223: Cancelled RelWithDebInfo builders trigger autobake builders

This was a nice feature in the past, when playing whack-a-mole
to stop a build and immediatly trigger one that will deliver packages on CI.

Now, with MDBF-1200, we may forget this childhood game,
and allow the build canceller to stop older build requests
without any side-effects (i.e. triggering other builds).

We still don't stop failed tests from triggering package builders,
and it is ok; dev's should decide if the generated packages are worth a dime.
