NIFI-6512 Relationship Name ellipsis Not Working

[patricker]

Description of PR

In the Connection Configuration UI, the relationship name list is formatted by calling the ellipsis jQuery plugin, but does not work because of a CSS style being applied to the list.

This causes long relationship names to be cut off abruptly instead of having the ellipsis applied.
