WeldJpaInjectionTestCase fails in the jpa layer test suite

We removed the microprofile-metrics from jpa layers. This removal affected to WeldJpaInjectionTestCase test execution, which uses CDI to inject beans.

This test was being executed with combining jpa and datasources-web-server, however, datasources-web-server does not add CDI. We need to use the upper base layer to make the test pass.
