Confusing, if not downright wrong, warning message
### Describe the bug

I run my app in dev mode. I change a build time property in `application.properties` and the application properly restarts but I get the following warning in the console:

```java
2022-02-10 09:57:08,244 WARN  [io.qua.run.con.ConfigRecorder] (Quarkus Main Thread) Build time property cannot be changed at runtime:
 - quarkus.operator-sdk.crd.apply was 'true' at build time and is now 'false'

```

What is this message trying to tell me? What is the state of my property, i.e. is it `true` or is it `false`?

### Expected behavior

A clear message as to what happened.

### Actual behavior

The currently ambiguous or wrong message.
