Fix the group text attributes defect in UB

[dbur]

In UB when a selection of multiple text objects are grouped most of them just dissapear.  They do not re-appear when the group is ungrouped.

This is a pain when mutiple structures with text objects exist and need to be replicated in a design.

I reported this as a bug a couple revs back when I was a beta tester and was told it was fixed for the next rev, but it was not.  I updated the defect report with that info, but noone seems to have noticed.
