#2305 Rename a `scss` file crash the watcher

[Anonymous]

Originally created by: francoismassart

While trying to find out what fails when adding a new scss file (see [#2296]), I did try to rename a file while node-sass is running in watch mode and it crashes:

node_modules/node-sass/bin/node-sass:266
    handler(watcher.deleted(file));
                    ^

TypeError: watcher.deleted is not a function
