fix: continue instead of break in the submit task loop (#87)

# fix: continue instead of break in the submit task loop

This PR makes the submit task future `continue` instead of `break` when it is done finishing its retry loop.
It was incorrectly breaking out of its submit loop after finishing one `retrying_handle_inbound` call.

Fixes ENG-1077
