OpenShift server adapter should be ok with a git project with proper git remote

1. create/clone openshift application without JBT
2. import this into JBT and team share it with git
3. add user in openshift explorer as used in #1
4. Create openshift server adapter using the project imported

Currently #4 keeps saying the project does not match anything because
it assumes every git project was created with openshift wizard.

That restriction could/should be lifted.
