Merge pull request #359 from mwringe/LIVEOAK-407

LIVEOAK-407
Add synchronous initProperties() to match properties() for update on SynchronousResource
Remove unused service name
Modify ApplicationClientsInstallService to remove itself on completion, as it doesn't need to be retained
Make SynchronousResource.initProperties() default to calling properties()
