MrMelbert 149063dd1b Fix Eye Chart being unobtainable (#89952) ...

## About The Pull Request

Turns out you need to set sign change name for it to be selectable on
blank signs

I thought this was a big footgun so I just added logic to have signs
default to their name if they are editable but don't have a change_name
set.

## Changelog

fix: You can make eye charts out of blank signs
