@AfterLRA notifications recently introduced in the specification are being delivered twice when the LRA is finished.
There is actually a TCK test testing this for non JAX-RS participant so this is blocking PR 1450.
The failing TCK test `TckParticipantTests#validWebApplicationExceptionReturnedTest` asserts now that `@AfterLRA` method is called once after the LRA is finished - https://github.com/eclipse/microprofile-lra/blob/master/tck/src/main/java/org/eclipse/microprofile/lra/tck/TckParticipantTests.java#L82. This means that the specification prohibits that AfterLRA method is called more than once for one LRA.
This isn't failing current TCK as the assert is present in the non-JAX-RS TCK (PR 1450)
