Beta: Fix for mapinfo failing in Torghast and other zones without proper coordinates
On Beta in both Torghast and at the start of a new player experience (first 3 min on the ship) you get spammed with errors every time you move. Error produced is:
7255x ElvUI\Core\MapInfo.lua:111: attempt to index field '?' (a nil value)
[string "@ElvUI\Core\MapInfo.lua"]:111: in function `GetPlayerMapPos'
[string "@ElvUI\Core\MapInfo.lua"]:78: in function `MapInfo_CoordsUpdate'
[string "@ElvUI\Core\MapInfo.lua"]:40: in function `func'
[string "@ElvUI\Core\Core.lua"]:1161: in function <ElvUI\Core\Core.lua:1156>This PR adds a guard against empty coordinates, thus effectively making the zones "restricted" as far as the consuming functions are concerned.
