Fix T37534 remaining issue: auto-enable bevel weight view
whenever enter edge bevel weight editing.

This is what happens when one makes an edge sharp, for instance.
The edge bevel weight display is not on by default for performance
reasons, but seems reasonable to enable it when user indicates
interest by editing bevel weight values.
