PubSubIntegrationTest fails with "Invalid grant: account not found"

Issue in `Wildfly Camel :: Feature :: Modules` was discovered when prod build of 7.10 was executed. Basic fix (https://github.com/jboss-fuse/wildfly-camel/pull/466) is  merged to allow prod build to continue. But there are some test failures probably caused by this PR and they have to be taken care of:

[ERROR] GoogleMailIntegrationTest.messages:185 » CamelExecution Exception occurred dur... [INFO] [ERROR] Tests run: 567, Failures: 0, Errors: 1, Skipped: 26
