test: remove unused assert module imports

Many test modules load assert but do not use it. This change removes
those instances.

It also removes a handful of other unused variables when they were
nearby.

test-domain-exit-dispose-again by changing its logic to test that
process.domain was cleared properly in case an error was thrown from a

However, it became clear when reviewing a recent change that refactors

Thus, this change adds the original implementation of
test-domain-exit-dispose-again back, with comments that make its
implementation easier to understand.

It also preserve the changes made by

http: remove excess calls to removeSocket

socket.destroy() triggers a 'close' event from the socket which triggers
the onClose handler of HTTPAgent which calls self.removeSocket(). So by
calling self.removeSocket() prior to socket.destroy() we end up with two
calls to self.removeSocket().

If there are pending requests, removeSocket ends up creating a new socket.
So if there are pending requests, each time a request completes, we tear
down one socket and create two more. So the total number of sockets grows
exponentially and without regard for any maxSockets settings. This was
noticed in https://github.com/nodejs/node/issues/4050. Let's get rid of
the extra calls to removeSocket so we only call it once per completed
request.

tls_wrap: inherit from the `AsyncWrap` first

`WrapperInfo` casts pointer in JS object's internal field to
`AsyncWrap`. This approach fails miserably for `TLSWrap` because it was
