ConfigProperty injection for Provider<CustomClass> is not working

Using https://github.com/rsvoboda/rsvoboda-playground/tree/master/microprofile-config-custom-converter-and-source application.

This is working on OpenLiberty, but not on WF server. TBH I don't see reason why this shouldn't be working on WF too.

First I thought it's problem in convertor not being picked up properly, but the problem seems to be triggered by https://github.com/rsvoboda/rsvoboda-playground/blob/master/microprofile-config-custom-converter-and-source/src/main/java/org/experiments/rsvoboda/system/SystemConfig.java#L18

WF throws following error when accessing http://localhost:8080/microprofile-config/config/properties
{code}
Caused by: org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001334: Unsatisfied dependencies for type Email with qualifiers @ConfigProperty
	at org.jboss.weld.bean.builtin.InstanceImpl.checkBeanResolved(InstanceImpl.java:241)
	at org.jboss.weld.bean.builtin.InstanceImpl.get(InstanceImpl.java:113)
	at org.experiments.rsvoboda.system.SystemConfig.getEmail(SystemConfig.java:26)
{code}

When I change the code to avoid javax.inject.Provider usage, things start to work as expected.

When trying the example please follow https://github.com/rsvoboda/rsvoboda-playground/blob/master/microprofile-config-custom-converter-and-source/README.md
CustomConfigSource has to be adjusted.
