REST endpoint codelenses should be computed from %dev.quarkus.http.port by default

Given a Quarkus application.properties containing
```
quarkus.http.port=8080
%dev.quarkus.http.port=9090
```
When debugging the application (i.e. launching quarkus:dev), the dev profile is being used, so the app starts on port 9090. Yet the codelenses ignores the %dev.quarkus.http.port value (shows 8080 for me, because of #307).
