Ability to change DesktopEntry about mpdris2

[muffinmad]

@grawity I have the following in my /usr/bin/mpDris2:

    __root_props = {
...
        "DesktopEntry": ("ncmpcpp", None),
...
    }

Clicking on mediaplayer extension and on GS media notification works fine. Where can I see two entries for the same app?

DesktopEntry is also used for other things, such as selecting the displayed name & icon. Changing it would mean you'd end up with two entries for the same app (with one of them being mpdris2 in disguise).
