"show-location" action does not work properly
I'm working on the Send To dialog in GNOME Maps, and one of its features is opening a location in Weather. This is done by using D-Bus to activate the "show-location" action. However, there are several problems with that in Weather:
- It currently doesn't work at all, due to some missing function parameters (fixed in !20 (merged))
- Adding a location opens a new window, even if there is already a Weather window open
- Recent locations can be duplicated with this method
