#50 Bug after reloading in outland dangeons

[Artur Shuranov]

Error occures after reloading interface (for example, with '/reload' command) in outland dangeons. Error occures if 'Location' is visible on titan panel.
Can be fixed by replacing 'mapID ~= nil' with 'mapID ~= nil and C_Map.MapHasArt(mapID)' in classic\Interface\AddOns\TitanClassicLocation\TitanClassicLocation.lua (replace in 2 places in this file).

Leatrix-maps had similar issue, it is well explained here https://github.com/leatrix/leatrix-maps-bcc/issues/16 in the last post - about mapID in Outland dangeons.
