Adds a check for validity of the file node index before running an
XQuery.

In evaluateResult(), QXmlQuery binds to a QXmlNodeModelIndex variable
without checking if it's valid. This causes an assert to trigger if
the default directory that the example tries to open does not exist.
In this case, m_fileNode has the default (null) value when
evaluateResult() is invoked on QComboBox::currentIndexChanged()
signal.
