Avoid erroneous fanout-size and primary output updates

[hriener]

This PR makes minor changes to the logic of take_out_node, replace_in_outputs, and substitute_node:

• Avoid fanout-size updates when deleting a node, which has already been deleted before.
• Avoid updating primary outputs if the update propagates from a dead node.
• Avoid update propagation from dead nodes in the hash.

A new test case ensures that take_out_node can be invoked twice on the same node without recursively affecting its fanins.
