fix(cli): --dry=fail should also fail when either added or removed typings

[chelkyl]

Now correctly checks even if only added or only removed typings. Sorry for the bad logic in the original PR.

Coverage remained the same at 100.0% when pulling 0d5589d on chelkyl:fix-dry-run-fail into 3b445b3 on jeffijoe:master.

The CI is failing due to Node 18 being the new stable, but not sure why?

[chelkyl]

Looks like the build config needs to be updated to choose a distribution newer than xenial.
See: nodejs/node#42351 (comment)

From the NodeJS repo BUILDING.md, Linux binaries are now built on RHEL 8 and the footnote says:

Binaries produced on these systems are compatible with glibc >= 2.28 and libstdc++ >= 6.0.25 (GLIBCXX_3.4.25). These are available on distributions natively supporting GCC 8.1 or higher, such as Debian 10, RHEL 8 and Ubuntu 20.04.

I see, thanks! Would you mind updating the travis config in this PR? 😄

[chelkyl]

No problem! Updated to focal and it is passing all but 14.
The build failure seems to be a network fluke or something because the error is read ECONNRESET.

[jeffijoe]

Nice, thanks! I’ll merge and release tomorrow, appreciate it!
