Integrity check "Abbreviation Detection" detects abbreviated names for journals and booktitles based on the internal list instead of only looking for "." signs.

Based on the issue it is ok to remove this checker, I guess. However, doing so you also removed a localization entry, which you need to purge from the localization files.

I agree that the implementation is skewed and such a check does not make real sense for the booktitle field. However, I kind of like the idea that one can ensure that all the journals are in the non-abbreviated form. Thus I would prefer if you could fix the code instead of removing it completely.
Shouldn't be hard since we already have a nice method to determine if a journal is abbreviated according to our huge list of journal names:

jabref/src/main/java/org/jabref/logic/journals/JournalAbbreviationRepository.java

Lines 46 to 48 in 6bb21d4

	public boolean isAbbreviatedName(String journalName) {
	return abbreviations.stream().anyMatch(abbreviation -> isMatchedAbbreviated(journalName.trim(), abbreviation));
	}

Updated. Please have a look.

The code looks fine, but you need to resolve a merge conflict.
