renames class MemberRegistrationIT -> MemberRegistrationTest

[pedroqueiroga]

This change is needed to ensure mvn clean test -Parq-remote or mvn clean test -Parq-managed is able to run as instructed on kitchensink's quickstart 6.2.1. Arquillian section. This change might be needed for all the other classes listed below, but I have just found out about wildfly and have only experimented with this project. If interest is shown, I could test and update the other ones too.
