"StartArguments" text box and warning showing despite being empty

[drewnoakes]

We have a feature that attempts to warn the user when they have a StartArguments property in their project. It is showing whenever you create a new "project" launch profile.

1. Create a new .NET Console application
2. Open the launch settings dialog
3. Click "New" -> "Project"
4. Notice the "StartArguments" and warning appear

Note that if you dismiss the dialog and reopen it, the warning disappears.
