Name changes causing update failures

[Derpthemeus]

If a player changes their name and somebody else claims their old name, highscore entries with this name will not be removed

Example: Alice is named "foo" with 500 points on Aatrox, enough to be on the highscore list Bob is named "bar" with 100 points on Aatrox, not enough to be on the highscore list Alice changes her name to "baz" Bob changes his name to "foo" "foo" is still listed on the highscore list for Aatrox, even though Bob does not have enough mastery points to be on the list

Turns out this issue still isn't fixed. The current approach only warns if a player has lost points, not if a different player (with the same name but a different ID) has taken their spot. This issue will likely just end up getting fixed when I add automatic score updating soon™
