In JabRef 5.0--2020-03-09--6bff936 changes in preferences -> entry table -> Format of author and editor names updates the column. E.g., changing from "Firstname Lastname" to "Lastname, Firstname" is immediately shown.

In the current master (built from Intellij on Mac OS 10.15.4 the 23rd of May) changes requires a restart before the author column updates.
It also does not work with
JabRef 5.1--2020-05-22--ef2a31c
Mac OS X 10.15.4 x86_64
Java 14.0.1

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

Steps to reproduce the behavior:

1. Attempt to change the style of the authors' column
2. Press save
3. Notice that the format of the authors' names are not changed
4. Easiest to spot with "Firstname Lastname" to "Lastname, Firstname"
