[Manager] Fix fields populating on 'Add Project' wizard on launch

When opening 'Add Project' wizard it shows next fields empty:
Research area, Organisation, and Web site.
This happens because of EllipseStringIfNeeded() function that truncates the string to 0 symbols because the wizard window was not constructed yet and has undefined size.

This fixes #2444.
