Do not evaluate deleted borders.

This bug was showing when fast toggling between advanced<->basic in
config dialogs.

Note, however, that there are a remaining alien bug with fast
toggling. It's aborting due adding evas object as member of another
from other canvas, which is not allowed. I tried to debug it and it's
REALLY weird, the advanced or basic create_widgets() are being called
twice, from inside the same function, like if the create_widgets() was
calling itself, but the code do not do that, I traced some that would
happen from e_widget_button_add()!!! Like if we had threads of were
being preempted from nowhere, really strange... seems like a stack
corruption :-(
