1. Take any snapcraft.yaml with one part, like "qt-app"
2. Run snapcraft prime
3. Add an "install: mkdir -p $SNAPCRAFT_PART_INSTALL/foo" line to your part
4. run snapcraft prime
you will see:
Skipping pull qt-app (already ran)
Skipping build qt-app (already ran)
Skipping stage qt-app (already ran)
Skipping prime qt-app (already ran)
-> Your part didn't rebuild, there isn't a "foo" directory in prime/ eitehr.
What should happen:
the qt-app part should be marked as dirty and forced cleaning.
