Looks good for me.

I found something that is not related to this PR. But need to be fixed in next phases.
Buy some reason drupal-check didn't catch deprecation function usage https://github.com/OS2Forms/os2forms_forloeb/blob/fix_comments_plus_indentation/os2forms_forloeb.module#L97

And this related for all modules where drupal-check is using to check deprecation usage.

I have handled the deprecation notice per your review, thus the CI check passed. It was straightforward getting Travis to run. Great review and focus on high code quality.
