Microsoft in a recent update to SSMS put the Performance Dashboard directly into SSMS so you no longer need to manually install it on remote servers. Microsoft hasn't included a script to remove it, the easiest way to remove it is to manually edit the original script and rerun it
Lucky for you I can save you 5 minutes of editing
