Enable Integration test for Fuse 6.3.0.R1

All integration tests to create project using 6.3.0.R1 Fuse version are failing but only with automated tests, not manually.

I merged the support for 6.3.0.R1 but it would be nice to be able to find the origin of the reason and to reenable them.

To play the tests and see what is the failure, just uncomment this linehttps://github.com/fusesource/fuseide/blob/master/editor/tests/org.fusesource.ide.projecttemplates.tests.integration/src/main/java/org/fusesource/ide/projecttemplates/tests/integration/wizards/FuseIntegrationProjectCreatorRunnableIT.java#L103
