Bug Report: deployment fails with NPE when MPC value is only available profiled

[poikilotherm]

Brief Summary

We use a MicroProfile Config lookup in a constructur. The setting is available from microprofile-config.properties, but only as a profiled setting: %ct.dataverse.siteUrl.

The deployment of Dataverse fails with an NPE because the resolver does not find a non-profiled value.

Expected Outcome

Just use the profiled value if no other value is present.

Current Outcome

Caused by: java.lang.NullPointerException: Cannot invoke "fish.payara.nucleus.microprofile.config.spi.ConfigValueImpl.getSourceOrdinal()" because "resultWithoutProfile" is null

Reproducer

I will at least provide a PR with a unit test demonstrating the fail. I will try to provide a fix as well.
