Fix bug 5744: http://bugzilla.lyx.org/show_bug.cgi?id=5744.

Crash with completion in mathed.

When deleting an inset, the stored DocIterator might contain a reference to a non-existent Inset and Text. Therefore, if we detect that the depth has changed, we are (for sure) not in the same paragraph, but we should make sure not to ask for the innerParagraph.
