GUI: Check the project after creation.

Earlier the GUI (project) went into some weird state after creating
a new project. The project could not be checked in any discoverable
way.

This commit fixes the above bug by automatically checking the new
project after the project dialog is closed. I think this is what
most users expect to happen.
