Often the parent project for a project needs to be resolved. The
parent project can be retrieved from a project by invoking
Project#getParent(). The problem is that this method may return null
for child projects of the wild project. This special case has to be
handled by every caller (if getParent() returns null and it's not the
wild project, the wild project is the parent). Similar code to handle
this situation is repeated in several places.
This change makes one implementation to resolve the parent project
reusable and removes duplicate code.
