ProjectWindow: Remove unnecessary code

Since projects without targets are special, this code apparently tracked
if hasTarget() changed due to a kitUpdate. But we are already connected
to targetRemoved() and checks whether a project has no target anymore.

Thus this code is redundant and can be removed.
