While working on the unit test for WFLY-7075, I noticed that PersistenceContext properties are not being passed correctly to the Injected EntityManager, we should fix that.

For Example:

@PersistenceContext(type = PersistenceContextType.TRANSACTION, unitName = "mypc", properties=

Unknown macro: {@PersistenceProperty(name="wildfly.jpa.allowjoinedunsync", value="true")}

)
private EntityManager allowjoinedunsyncEm;

Is passing an incorrect form of the property values.
