Reverting part 2 of 7970189ec93faf3ee71cf49e97529980bbd219aa
This completes the revert of that commit.

Without the DELETE when you tried failing over to a non-direct
subscriber you could end up with a loop in sl_subscribe after
the failedNode function returns.

ie before failedNode() sl_subscribed showed

set,provider,receiver
1,1,2
1,1,3
1,3,4
1,4,5
and after
1,4,2
1,4,3
1,4,2
1,4,5

notice 4=>2 and 2=>4
