Steps to reproduce:

1. Go to Projects > Create Project.
2. In the dialog box, enter an invalid Project Name (e.g. already existing in the system).
3. Correct the Project name.
4. In the Project Lead field, start filling in the user name and hit 'Enter' to use an autosuggestion option.

See that the username is not selected, and only the originally typed letters are saved in the Project Lead field.

Notes:

• this happens for all Project Templates;
• clicking an autosuggestion item with a mouse does populate the field correctly.
