Flaky TestWantlistRebroadcast test

[Stebalien]

The last step is collecting no messages, leading to a panic:

panic: runtime error: index out of range [0] with length 0 [recovered]
	panic: runtime error: index out of range [0] with length 0

To reproduce, run go test -count 100 -run TestWantlistRebroadcast.

Assigning myself mainly because I want to learn more about bitswap but probably I'm not the best candidate for this, so feel free to unassign me if we need this fixed asap.

@Stebalien I can't reproduce the error, is this issue still relevant?

go test ./internal/messagequeue/ -count 1000 -run TestWantlistRebroadcast -v

@schomatis : I'm closing since can't reproduce.
