Do not recognize file in workspace root as project

[vzhukovs]

What does this PR do?

This changes proposal improves behavior of file manager which works with files in workspace root. At first, additional check was added to avoid create project configuration when file is created in workspace root. And on the client side we don't show notification that project is created, when it's actually a file in workspace root.
