snapcraft fail to find built executable under prime $SNAP
Metadata
Current evaluation
Launchpad #1795171: crash was user error — app command used literal $SNAP/bin/ags. Maintainer @ogra gave the correct YAML (command: bin/ags), reporter confirmed; report later expired for 60 days inactivity.
Resolution: closed not a bug
Reason: No code change was made: maintainer @ogra explained that apps command paths are relative to $SNAP and supplied the corrected snippet ('command: bin/ags'), which the reporter confirmed worked. The bug was then auto-closed by ~janitor on 2018-12-02 with '[Expired for Snapcraft because there has been no activity for 60 days.]'.

Issue body
Hey, I got the error below when trying build a snap. The binary is under /home/username/git/ags-snap/prime/bin/ags and $snap/bin/ags
Priming ags
Sorry, an error occurred in Snapcraft:

Later Launchpad report of the same class of 'missing prime/bin executable' symptom in Snapcraft 2.43.1, likewise resolved by correcting the apps command path rather than a snapcraft fix.

| #1884683 snapcraft fail app | snapcraft (launchpad) | open | Snapcraft 2.43.1 crashed on missing executable /bin/Sastreria; newer code added invalid-command handling, and the maintainer says the Snapcraft snap fixes it, but no retest was posted. | |
| #1812435 python snap fails to build no such file or directory in prime/bin | snapcraft (launchpad) | open | Snapcraft 2.43.1 fails while priming because apps.command references a missing prime/bin/mockpyairpulse; the supplied YAML lacks evidence about the source package's entry point. | |
