Propagate cancellation token in async Merge - #880

Conversation
`Merge` created its enumerators and materialized the initial list without the token from `await foreach`, so cancellation was not observed by the source sequences. `Interleave` already plumbs the token this way.

Mergeobtains its enumerators and materializes the initial list without the token coming fromawait foreach, so a cancellation is never observed by the source sequences.Interleavehad the same problem and was fixed in 8f587ac, this applies the same plumbing toMerge.The added test fails on
mainand passes with the fix.
