Fix problems in BibTeX replacements, e.g. {\ss} for ß

Fix PDF url in ACS Publications.js and clean up

The xpath for the PDF url (itemOpts.pdf) did match with
two nodes and therefore outputting a concatenated non-valid
string for it. This is fixed by focusing on the first match.

Additionally try to enable PDF saving in multiples directly.

Moreover, delete the different parts for High-Res PDF resp
PDF Plus with Links, which does not exist anymore.

This solves zotero#1966 now completely.

When accessing via an HTTPS proxy, the site can still embed HTTP URLs,
which will be reproxied as HTTP. If the proxy supports HTTP, that's
fine, but if it doesn't, saving will fail, so convert those to HTTPS
when the current URL is also HTTPS.

Fixes zotero#2004

The new replacement is more strict but will still work for the
example given in zotero#683.

Added more test cases also the initial one together with an
example using the sharp s and one Islandic example.

 [OJS] Delete wrong value "1" for journal abbreviation

This is used by some OJS instances.

Restrict GitHub

This fixes zotero#1998.

 Update Amazon.js

The function getAuthor() was never used also
not at the very start of this translator and
therefore now deleted completely.

This fixes zotero#1788.

Switch YouTube.js to more direct extraction

This fixes https://forums.zotero.org/discussion/78670/open-journal-systems-translator-journal-abbreviations

Update (most) test cases and fix thereby also a problem with
missing abstract.

Two test cases are not yet updated, because the OJS instances
seemed not to produce much meta tags. I have written them and
ask for better support of biblographic metadata.

The relevant JSON data is now in the body and more
nested to easily extract from. However, it seems that
all information (except tages whic aren't great at all)
can also been extracted otherwise.

The tests are not working in Scaffold and multiples seems
also not to work properly at all.

This fixes the problems reported e.g.
https://forums.zotero.org/discussion/comment/337315

- abstract will work in practice but currently not within
Scaffold
- switch detection to digital product class and use
storeID only if that does not work
- fix multiples of search pages and author pages
- update tests, add nits
- add test with gateway parameter

This solves zotero#1985.

Add alternative detection in Amazon.js

This fixes zotero#1936, i.e. when s=gateway is part of the url.

Fixes for eLibrary.ru
