We can `dns.lookup` a falsy `hostname` like `dns.lookup(false)`
for the reason of backwards compatibility long before(see #13119
for detail). This behavior is undocumented and seems useless in
real world apps.
We could also make invalid `hostname` throw in the future and the
change might be semver-major.

These test cases in `test/parallel/test-dns-lookup.js` send
dns requests and depend on the results, which could fail
if the DNS service for invalid hosts is hijacked by the ISP.

This commit removes `common.crashOnUnhandledRejection()` and adds
`common.disableCrashOnUnhandledRejection()`.
To reduce the risk of mistakes and make writing tests that involve
promises simpler, always install the unhandledRejection hook in tests
and provide a way to disable it for the rare cases where it's needed.

A error message should always be non-enumerable. This makes sure
that is true for dns errors as well. It also adds another check
in `common.expectsError` to make sure no other regressions are
introduced going forward.

There is actually no reason to use `assert.doesNotThrow()` in the
tests. If a test throws, just let the error bubble up right away
instead of first catching it and then rethrowing it.
