To work around the issue that a few AVRs blindly append parameters with an ampersand. This also allows us to get rid of the search logic workaround. Furthermore the vTuner API also hacks around the issue this way. So this seems like the correct way to handle that even if it looks ugly.

We need this bogus parameter because some (if not all) AVRs blindly append additional request parameters
