Retrigger build after non-default build
Retrigger build after non-default build

Automatically trigger a package build after building non-default
commit. This is necessary so that when a new change gets pushed
to GitHub we check the correct branch for changes. Otherwise, after
e.g. building refs/tags/mytag, we check for new changes based on the
last build (i.e. refs/tags/mytag) which of course returns nothing.
