Add piped filter for user names in template for List View

[jakob-bagterp]

If you have added a user on a page with the User Picker as data type, then the default return value is just the user ID (i.e. -1, 1, 2, etc.) in the List View. It's more useful to get the user's name, which could be done similarly as the ncNodeName filter in the template.

So, instead of just getting the user IDs in the List View...

... you would configure the view with a piped filter {{ value | ncUserName }}...

... and then the user ID would be transformed into the user name by looking up the ID in the list of users.

PS: As I understand it, ncNodeName only checks for Media, Member, Document, but not User via the entityResource service.
