java.util.ServiceConfigurationError: io.smallrye.config.SmallRyeConfigFactory when injecting same configuration parameter in multiple test classes

Describe the bug When injecting a config property annotated with @Configproperty(name = 'myproperty') and @Inject in two separate Test classes, it will run the test fine on the first class, but on the second class it will throw the following exception:

Disabling one of the two test classes means both classes run fine, so the tests themselves have no error. After removing the @Inject and @Configproperty(name = 'myproperty'), and hardcoding the value, both tests are running as expected. So the problem is clearly in the injection mechanism.

Note that this behavior was not with Quarkus 1.2 and started after upgrading to Quarkus 1.3

Expected behavior I can inject the myproperty set in applications.properties across multiple test classes and have my test classes all succeed.

Actual behavior Currently this injection only works for one class, and will fail once the second test class is starting.

To Reproduce Steps to reproduce the behavior:

1. Create two separate test classes and a config parameter in application.properties
2. Inject the parameter in both test classes
3. Watch the first test succeed, and the second one fail. Run them individually and the test cases both succeed.
