New project from Gitlab Export fails to set project name properly

Summary

When you create a project from a gitlab export, the project name is not properly created.

Steps to reproduce

1. Create a gitlab export for a project (I did it in my hosted gitlab to move to gitlab.com);
2. Create a new project in gitlab.com from an export;
3. Set the name to 'Foo Bar' and automatically the slug will be 'foo-bar'.
4. Choose the export file and create the project;
5. Note how after the project is created both the name and slug are 'foo-bar' - i.e. the selected project name was not propagated.
