Camera translation (#3747)

* citra_qt: correct spelling in configuration

* citra_qt/camera: Changed the order of the translation

The translation may not correspond to "couln't load" and "the camera", so create two cases which can get translated individually.
Also add a space after "the camera".

* citra_qt/camera: use the same syntax for the filter in "still_image_camera.cpp" as in "configure_camera.cpp"

* citra_qt/camera: the config should only get added if it's not empty
