Merge #4149

4149: Always send correct zoom dimensions r=heinrich5991 a=fokkonaut

It is required to reset the Target after it being used, in order to not trigger [this code](https://github.com/ddnet/ddnet/blob/master/src/game/client/gameclient.cpp#L1599-L1605), which would always send the m_LastZoom. This fixes it and always sends the correct zooming dimensions.
