Disable pagination in all places where we need all items.
Ideally we'd do multiple paginated requests until the needed items are local, but this is blocked by gitea/go-sdk#473. So this is a stopgap to get correct behaviour.
@lunny there are no conflicts.
Looks like conflict detection is broken again/still. #427 has the same issue. I think in both cases I did a local merge, and after pushing that Gitea started to show conflicts.
