[fix] remove usage of no longer existing names from lxml

Browse source 
In lxml 5.1.1 the private name `_ElementStringResult` in module `lxml.etree`
does no longer exists.

This code was written nearly a decade ago, its no longer clear what the
intention `_ElementStringResult` and `_ElementUnicodeResult` had been. It can be
assumed that these classes will no longer occur.
