`You shouldn't be here...` logic appears to be off

[euantorano]

Following this topic in which your plugin is used, there seems to be an issue with the logic found here: https://github.com/stewartiee/Steam-OpenID--MyBB-/blob/746f560f215313db466c1c1aab9d39fb96985c56/inc/plugins/steamlogin.php#L540

This function is hooked to misc_start so will run on all requests to misc.php - including ones completely unrelated to this plugin. The two if statements should be swapped so that the action is checked first, and then the user ID.
