Fix cell-var-from-loop in _send_catch_log_deferred

Replace lambda capturing receiver by reference with a default
argument to capture it by value, fixing a potential bug where
all deferred callbacks could reference the last receiver in the
loop instead of their respective receivers.

Removes the pylint disable comment and TODO that were suppressing
this issue.
