Merge torrust#875: Fix and improved bootstrap jobs module test.

9be9366 Fix and improved bootstrap jobs module test. (Gabriel GRONDIN)

Pull request description:

  On non-English operating systems, the source ``BadTlsConfig`` error message will be different from the compared message.
  This solves the problem by matching the enumeration itself, rather than relying on a string comparison.
