ADS Fetcher (Test) fails

[Siedlerchr]

Latest dev version https://github.com/JabRef/jabref/commit/955b94d7221e5ee3c102731f885eb395e1c2ad64

From what I see, the entry returned from the fetcher contains the field eid = {#10}

Should we separate the fetcher tests from the normal tests? Similar to the database and integration tests? This would enable a separation and keep avoid failing tests being unrelated to a certain PR.
