tdf#155951 sw: fix crash using XTextRange::getString() in selectionChanged()

XTextRange::getString() triggered selection change event,
resulting infinite recursion, when getString() used
in selectionChanged() of the listener.

Steps to reproduce (used by the unit test, too):

Add a XSelectionChangeListener to the document with a
selectionChanged() calling the getString() of the selected
text range. Select a word in the document editor using
the Ctrl-Shift-arrow keys.
