webdriver: fix test_parent_htmldocument to expect error and test invalid relative xpath (#10058)
 
When the context element is `document.documentElement`, and an attempt is
made to find elements from that context element using an XPath of `..`, a
snapshot is returned containing the `document` object. While this is
apparently the correct behavior for XPath, the WebDriver spec says that if
the object in the snapshot is not an element, we should return an error
with error code "invalid selector." The test_parent_htmldocument test in
both find_element_from_element.py and find_elements_from_element.py expect
a success in this case. This commit changes the tests to correctly expect
an error from the driver.
