Proposed patch for the bug. Suggesting review of NetBeans Dev Team.

For project located directly in the root of the drive(For example Network Drive)
masterfs fails to add a watch to the system resulting in the following errors in the log:

WARNING [org.netbeans.modules.masterfs.watcher.Watcher]: Cannot add filesystem watch for W:/: java.io.IOException: Unable to open null: 3

Patch for the problem is attached(Algorithm used to find the 'root' of the 'path' didn't count the special case there 'path' itself is an root which is shorter in length than an assumed minimum.

Fixed.

I've also added logging of an info message, as registering listener for drive root
can be problematic in some cases.

Thank you very much for reporting and for the patch!
