In project wizard, hitting the cancel button stops the job but wont cleanup the project (-resources) that were created.

Steps to Reproduce:
0. Install latest version of Jboss Developer Studio from https://devstudio.redhat.com/9.0/stable/updates/
1. Login openshift with Jboss Developer Studio
2. Go to context menu New->Project
3. Enter project name "xiazhaotest", click on the Finish button
4. Click on the red cancel button while JBT is creating project, the wizard jumped back to the page on step3, but project "xiazhaotest" is in fact created

Actual Result:
Cancel button did not work in create project wizard of Jboss Developer Studio
project "xiazhaotest" is in fact created

Expected Result:
Cancel button should work in create project wizard of Jboss Developer Studio
project "xiazhaotest" should not be created
