BUG-981: Fix XML serialization test

Since commit 7624eedc495e85d12c2c2c56efb09dfd9406f977 changed XML
resolution rules such that XML namespace is required to properly
identify a node.

This broke serialization tests, which did not provide module/revision
identification -- which meant serialized data was being handled by
String encoder. The string encoder does not do the right thing for
arrays -- which broke the bits and binary encoding tests.

Fix the tests to specify module/revision, thus matching conforming to
schema.
