Break early when delete happens in outdated state
A panic could happen when multiple delete messages are sent one after another without waiting until there are no messages left to be deleted: panic: runtime error: makeslice: len out of range goroutine 1 [running]: git.sr.ht/~sircmpwn/aerc/lib.(*MessageStore).Update(0xc000592e00, 0xa8fe60, 0xc0003340f0) /go/src/git.sr.ht/~sircmpwn/aerc/lib/msgstore.go:222 +0x5b8 git.sr.ht/~sircmpwn/aerc/widgets.(*AccountView).onMessage(0xc0000a0460, 0xa8fe60, 0xc0003340f0) /go/src/git.sr.ht/~sircmpwn/aerc/widgets/account.go:251 +0x307 git.sr.ht/~sircmpwn/aerc/widgets.(*AccountView).Tick(0xc0000a0460, 0xc0001496b0) /go/src/git.sr.ht/~sircmpwn/aerc/widgets/account.go:90 +0xa1 git.sr.ht/~sircmpwn/aerc/widgets.(*Aerc).Tick(0xc0000a9f40, 0xc000020501) /go/src/git.sr.ht/~sircmpwn/aerc/widgets/aerc.go:123 +0x91 main.main() /go/src/git.sr.ht/~sircmpwn/aerc/aerc.go:182 +0x5bf The make that blows up is: uids := make([]uint32, len(store.uids)-len(msg.Uids)) This change simply checks whether the make is going to be valid before starting to work on the actual delete. If there are more messages queued to be deleted than what's left in the store, then we're obviously in an inconsistent state, ask for an update and break.
