Upgraded projects do not display version number in Launcher

To reproduce:
- Create a project in version 4.6 and then close the editor
- Create a new project with the 5.0 beta 21 editor
- Go to File > Open other
- Locate the project that you created in 4.6 to open it
- A pop menu will ask you whether you would like to upgrade the project
- Upgade the project
- Close the editor
- Open the editor and observe that the project that you upgraded does not dispaly a version number

Please see attached screen shot for details.

Expected result: As a user I would expect the Launcher to display the correct 5.0 version number that the project was upgraded to.
