[OE-core] [PATCH] testimage: fail if no package manifest is found

[Stefan Stanacar]

Sometimes we may forget to actually build the image
we want to test (when testimage task is called manually).
Instead of an ugly traceback we should fail nicely.
The manifest is written after the rootfs so this ensures
the image was actually built.
