Merge lp:~georgesofianosgr/switchboard-plug-pantheon-shell/fix_duplicate_wallpapers into lp:~elementary-apps/switchboard-plug-pantheon-shell/trunk

[George Sofianos]

Check if wallpaper is already located in local background
directory before cloning it

[Zisu Andrei (matzipan)]

Code looks good. Haven't built and run.

review: Approve (code)

[MarkoD (markodolar)]

It compiles and works. Set wallpaper contract and selecting wallpaper in switchboard plug does not copy file anymore when selecting from ~/.local/share/backgrounds.

review: Approve (compile and functional)
