Renaming a group via groups interface does not change the group name in the interface

[Andrew-Lev]

JabRef 4.0-dev
Linux 4.4.0-92-generic amd64
Java 1.8.0_131

Steps to reproduce:

0. Open group interface. (Groups -> toggle groups interface)
1. Create a group
2. Add an item to the group
3. Right click on the group in the group interface -> edit group
4. Change the group name

Group name in the interface stays the same. If you check the group name by selecting an item and going to its Bibtex source you can see the change there.

When you close and expand the group, the change should also be visible. No idea though why it is not visible immediately. The same issue occurs if you assign an icon or color to the group

These bug still exists, I will work on it.

When I press edit group that show org.jabref.model.groups.AbstractGroup#name instead of org.jabref.gui.groups.GroupNodeViewModel#displayName, why? What's the difference between them?

The displayname is a formatted version of name. For example, if name contains latex commands like Hell\'{o} then displayname is the unicode version Helló.
