• Mandatory: I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

When entries are marked and sorted by a special field, "toggling" the special field of these entries does not work.

Steps to reproduce the behavior:

1. open the file jabref-authors.bib (https://github.com/JabRef/jabref/blob/master/src/test/resources/testbib/jabref-authors.bib)
2. display the columns of the specials fields (options -> preferences, tab Entry table)
3. mark a small set of entries as "Relevant"
4. sort entries by "Relevance" (by clicking on the column title), so that the marked entries are displayed at the top of the entry table
5. select the entries marked as "Relevant"
6. right-click and select "Toggle relevancy".
   ==> Only a portion of the selected entries have their "Relevance" status toggled.

Note: same faulty behavior with the other special fields (Read status, Rank, Quality assured, Priority, Print status)
