Remove deuterocanon tests

[Enkidu93]

Fixes sillsdev/machine.py#174.

I didn't see any problems in the logging from the tests, so at least at this point, I think we've resolved any issues that these would have caught. The only problems I noticed were with the tests themselves.

src/SIL.Machine/Corpora/ScrVersExtensions.cs line 11 at r1 (raw file):

        /// Gets a list of references (verse references) for the specified book.
        /// </summary>
        public static IEnumerable<VerseRef> GetReferencesForBook(this ScrVers scrVers, int bookNum)

If I understand correctly, you are removing this because it is not a part of machine.py? (as well as the fact it was only used by tests). I couldn't find any code on GitHub that use this method, but that doesn't mean that no one is necessarily using this function.

Code quote:

public static IEnumerable<VerseRef> GetReferencesForBook(this ScrVers scrVers, int bookNum)
