Running disconnect slash command even after the account is disconnected shows wrong error.

If the user is already disconnected and still runs the command "/drive disconnect", the user receives the error that the account is disconnected. Instead, the error should be that the account is already disconnected.

@AayushChaudhary0001 this is fixed in master.

This issue has been re-tested and I wanted a small enhancement here.
