Breaks on cross-device setups

[nCrazed]

I recently moved my project files to a different device which resulted in not longer being able to fire up the vagrant VM.

The error points to vagrant-phpstorm-tunnel/configurator.rb:22:

 File.link(source_path, destination_path)

In my case this ends up being something like this:

 File.link('/dev/sda3', '/dev/sdb1')

Which leads to an illegal attempt to create a cross-device hard link.
