LRA api-particpant quickstart needs aligning with the latest MP LRA spec changes

This quickstart depends on LRAParticipantDeserializer to recreate participants during crash recovery but MP LRA issue #61 has removed this class. The alternative registration mechanism is still outstanding see the comments on issue #35 for a discussion of the new way of registering participants.

Until a PR is raised for this issue I would like to disable the quickstarts that utilise LRAParticipantDeserializer.

Note that this has only just become an issue since previouslythe Narayana implementation of LRA depended on a specific snapshot build in the eclipse repo (since the LRA spec is in flux), but snapshots are purged after a month so the old way of registering participants is no longer available.
