[BLUEJ-1061] Trying to save a project inside itself causes a lot of problems
Open a project, then use "save as" to save in C: in a folder called "myproj". Next, do save-as again, and save as "myproj" with the parent folder set to "C:\myproj", i.e. save the project inside itself with the same name. BlueJ will recurse indefinitely trying to save forever-nested myproj items. We should spot this case, and not let the user save the project inside itself.
