- some extra generators for domain-specific data like NANPA-compliant
  phone numbers, Bandwidth media URLs, and JIDs (could be better, but
  nobody's perfect)
- Rake test tasks split into `unit` and `property` (existing `test`
  target runs both and is still the default)
- `property` target picks a random seed, then uses that seed to set
  `--seed=` (for minitest) and `srand` (for rantly). downside: you can
  only seed a whole test, you can rerun just one property with the same
  generated input. sad.
- `rake property` will, by default, collect failing seeds into
  `test/stubs`

turns out you need to set it in both test_helper and in em
- sgx_bwmsgsv2 references ARGV[0], so must set it before
requiring
- but each  test runs in its own fiber, and fibers don't share ARGV

fails, at least under ruby 3, without this

When text is empty/nil and there is no media, return 400 instead of
falling through to message construction with nil text.

When jparams['to'] is an empty array, return 400 instead of
falling through to message construction.

When the webhook references a phone number with no Redis JID mapping,
the handler returns 403 and writes no XMPP stanza.

this does not change any functionality, it removes a case where we
initially lie about which values is `others_num`

these types do not exist in V2, which can be verified either by the
reading the bandwidth docs here[0] or by reading the commit message of cd6e0df

Add a ResendIn message event type that records the original stream ID
and bandwidth ID without duplicating body or media fields. The webhook
handler emits this event instead of a normal In event when the
X-JMP-Resend header is present.

except we also unescape each individual tag part?

each test runs on its own reactor. stopping it means that `assert`s are
never called, which meant that gateway shutdown was counted as test
success. no bueno!

includes the same fix as better-feature-order

so I stop accidentally blowing it away

rely on old, broken APIs from the stdlib
