Pubmed import should have quality check multiple times.

[bernhard-kleine]

When I imported from Medline today (PMID: 30096135) Jabref immediately went into decline. I know that the problem is related to #4323, but that problem resolved, I would argue that an import into Jabref should be cleaned in any possible way. If the author list is not bibtex conform, please make it so. When there is a standard like Bibtex, we should keep to that and not letting anything to deviate from that standard.

• [+] I have tested the latest master version from http://builds.jabref.org/master/ and the problem persists

JabRef 5.0-dev--snapshot--2018-09-13--master--e83680f18
Windows 7 6.1 amd64
Java 1.8.0_181

Steps to reproduce:

1. open any library in Jabref
2. import 30096135 ( a PLoS article) into the library
3. since the author list after the import does not conform to Bibtex, Jabref stops working. You can only shut down the program. Once you open that library again, it will fail again. I circumwent this using Jabref 4.1 to clean the author list.

@Siedlerchr Would it be much work to have the quality control to run on any medline import and avoid the tiny error since author list contains abbreviated firstnames withoud a dot.

[Siedlerchr]

I just added the author normalizer to the cleanup operations after import from medline. So the abbreviated names are now correct with a dot. Bu I just noticed in the ID 30096135 you gave there is inserted an extra space after the last name when importing

@Siedlerchr: Today I imported PMID 30836949. The first run of the Author normalizer works, but this entry needs a second run of the normalizer since the abbreviated firstnames are wrongly spaced:

Nielsen, Sofie K. D. and Koch, Thomas L. and Hauser, Frank and Garm, Anders and Grimmelikhuijzen, Cornelis J. P.

That is why I suggested to run it multiple times on the Authors. After a second run it looks like Nielsen, Sofie K. D. and Koch, Thomas L. and Hauser, Frank and Garm, Anders and Grimmelikhuijzen, Cornelis J. P.

[bernhard-kleine]

The double spaces between K. D. and between J. P. do not survive quotes and codes. Therefore , both times they look the same, but they are not. I wonder why quotes are edited at all in github?

[Siedlerchr]

Try adding them in multiple code lines, three backticks before the block and three after

[Siedlerchr]

The problem with the double spaces between the author initials should be fixed now as well in the latest master. Refs #4931
