fixed the issue where import hangs for ris files with "ER - " failed #7737

fixes #7737

The test file in issue#7737 like error1.ris and error2.ris have a same problem that the last line "ER - " with no line break(/n) , so it isn't eliminate by split("ER -.\n") , use split("ER -.*(\n)*") can solve this problem

Can you please add/extend the unit tests for that case?

This is not what I meant with tests. Have a look at the RISImporterTestFiles class.
It searches for test files in /src/test/resources/org/jabref/logic/importer/fileformat that ar named with RISImporterTest....ris
and have a corresponding .bib file with the same name

So you create a minimal RIS file with the ER at the end and a corresponding bib files
This way you can test that the import succeeds without errors

I did a follow up PR with the changes
