Open file windows don't get updated with new paths

[mhsallam]

If I have a file "scripts/app.js" and I decided to move it to a new location "app/app.js", if the file window was open while I do the transfer, the path of the opened file window will not get updated to the new location. This has caused me a lot of confusion when I edit the file through it's still-open window I finds out that the new updates have been persisted in the old file path instead of the new one.
