[patch] crash

[Alfredo Braunstein]

Open the UG, click on the first footnote -> crash

The problem is that the bv_owner of the text is set on InsetText::dispatch,
but the insetHist check is done before that.

The attached solves it, even if it doesn't seem the right solution. 
bv_owner -> bv() changes were good to find the crash.
