Ensure wasmcloud-operator works with wadm applications without version specified

[joonas]

Since wadm v0.12.0 it has been possible to leave the version annotation off from the Application manifest, we need to verify that the operator can successfully deploy and modify applications that do not have it set.

Am getting this error with wadm v0.12.1:
