Check if findX3DDoc() succeeds

[eamanola]

regarding issue:

https://github.com/x3dom/x3dom/issues/1200

Summary: sometimes this._nameSpace is null

Changes: Check if _nameSpace exists, and that doc is found, before proceeding, so the script wont crash

Tests seem to run ok, at least no error messages. Should I pay attention to something in particular.

They all give this on load, but probably irrelevant:

XML Parsing Error: syntax error
