    Frontend-GNOME: fix error handling for image parts in MessageTextView.InsertToBuffer()
    
    The InsertToBuffer() overload for ImageMessagePartModel is not returning when
    the URL of the image fails to parse. Thus the code control flow continues and
    then calls AddAlternativeText() a second time. Adding a return statement in the
    catch block fixes this issue.
