Possibles for a poll are not scoped per poll in terms of position
I noticed that removing a RankedVotePage is significantly slower than the other page types. Turns out this query is slow:
SQL (475.7ms) UPDATE `possibles` SET `position` = (`possibles`.`position` - 1) WHERE (1 = 1) AND (`possibles`.`position` > 14738)
So i was wondering why this is not scoped by the poll... We are changing the possition of all possibles across all polls.
Turns out every position is only occupied once in a global way. Obviously that keeps the order intact. But it also means shuffling all other issues around in case one removes or moves one.
