Remote development does not resync on application.properties change

[jclingan]

Describe the bug
mvn quarkus:remote-dev does not recognize when only an application.properties file changes (and no other changes). Therefore, no code sync happens. However, if I change source code and application.properties, the property file does get synced.

JDK 11, Quarkus 1.6.1.Final

Expected behavior
When I change an application.properties file and hit the REST endpoint, I expect to see the new property applied.

Actual behavior
The property does not get synced and therefore is not applied.

To Reproduce
Feel free to start here, which is a bare-minimum remote-dev project. Just add code to inject the greeting ("Hello") from a value in the application.properties. Once that works, just change the greeting in application.properties and reload the endpoint. application.properties will not be re-synced.

Additional context
I'm a really nice guy.

I could not reproduce this reliably, but I think it may be a manifestation of the pre scan step being registered multiple times.
