Test for relevance pruning before validation

In step 3 of xforms-submit processing, we get a no-data error if relevance 
pruning eliminates all nodes.
In step 4 of xforms-submit processing, we do data validation,

The attached test should be added to the test suite as it tests for the 
step 3 no-data error.
It does so by pruning out an invalid but non-relevant node, so the test 
will also indicate a failure if an error other than no-data, such as 
validation-error, occurs.
