adapter.xml: improve element formatting in error messages

Previously, the namespace of an element would always be replaced by its
prefix if the prefix is known. However, this turned out to mask errors
in case the namespace is different from the one used by our SDK.
Thus, the function `_element_pretty_identifier()` is adjusted such that
it only replaces the namespace if it matches one of the namespaces known
to our SDK.

Partially fix #190
