Update samples for Scalatra after 2.2.2.

[ePaul]

PR checklist

• Ran the shell/batch script under ./bin/ to update Petstore sample so that CIs can verify the change.
  → just bin/scalatra-petstore.sh
• Filed the PR against the correct branch: master for non-breaking changes and 2.3.0 branch for breaking (non-backward compatible) changes.

Description of the PR

This just updates the scalatra samples without any functionality changes.
(This is a part of #4901 split out into a separate PR to see if CI likes it better than the whole thing.)

[ePaul]

Hmm, same error as mentioned in #4901 (comment).

It looks like this got broken with #3905 ... which forgot to update the samples, and is marked as "WIP".

[jimschubert]

@ePaul I opened ePaul#1 to revert the changes made to the Scalatra generator, which was changed by accident. #3905 shouldn't have affected other generators at all.

I rebuilt the Scalatra server sample locally and verified it worked after the changes. I didn't push that to the linked PR because I figured you'd want to re-run it and verify anyway.

[ePaul]

@jimschubert Thanks, merged this and updated the samples again. Let's see what Travis will tell us.

(It didn't affect other generators, but something based on the Scalatra generator was included in the Travis CI build.)

[ePaul]

Worked (on the second try, some NPM stuff seems to be nondeterministically failing). Thanks.

[jimschubert]

No problem. I've seen npm randomly failing on the build quite a bit. I haven't looked into it, unfortunately. I wonder if could use yarn instead.

[wing328]

I wonder if could use yarn instead.

Sure. Feel free to give that a try to see if it works better.
