Fix *All method which return a channel

[Quantumplation]

Each of these methods was panic'ing because of an attempt to send on a channel that was already closed.

This fixes that, and a few subsequent issues that arose. In particular:

• Let the loop break, rather than returning, to ensure we wait for each job to finsih before closing the channel
• Close the jobs queue so each worker finishes, and decrements the waitgroup
• Make the write to the quit channel non-blocking, since the quit channel doesn't get drained
• Now that the quit channel is non-blocking, we can make it size 1

This also updates several out of date golden test data

I can confirm this fix looks good and works for AccountAssociatedAssetsAll. I'd love to see this get merged!
