Mock Profile example code uses wrong function for wiping

[MattSchrubb]

--When done using mock profile on live servers: (Prevent memory leak)
MockProfile:Release()
GameProfileStore.Mock:WipeProfile("profile_key")
-- You don't really have to wipe mock profiles in studio testing

It should be:

-- When done using mock profile on live servers: (Prevent memory leak)
MockProfile:Release()
GameProfileStore.Mock:WipeProfileAsync("profile_key")
-- You don't really have to wipe mock profiles in studio testing
