Sub-task auto inherit parent's component after Greenhopper installation

The subtask will auto inherit parent's component during subtask creation as long as the Greenhopper plugin is enabled. The version and component synchronizer had been unchecked but it's still inherit the components from it's parent during creation.

Workaround at the moment:

• Under Enabled Project of Greenhopper configuration, exclude the project that not using greenhopper
• Disabled Greenhopper
