Update import tests

[dstillman]

Now that we're using import tests in translation-server CI, we should update tests for import translators so that they pass. We mostly just appear to be saving many more fields now than when the tests were generated, and there's some additional whitespace normalization in abstracts.

(At least, I'm assuming the test failures happen in Scaffold too and translation-server isn't somehow saving many more fields.)

Okay, I updated some of them in #1963. Let me second that I would appreciate when test cases are checked language-independent, because I otherwise have to delete the changes to German date formats which you will not see, see also zotero/scaffold#21

The test cases for Medline show duplicate tags, which we will not be saved in Zotero. Is there some step missing for testing? Probably related to zotero/scaffold#47

The itemIDs in the RDF-translator are not constant in different runs and therefore cannot easily been fixed.
