Removed double JS escaping of XPath strings
Removed double JS escaping of XPath strings

The XPath query should not be escaped as JS when passing it to the PHP
XPathAccessor of the underlying SahiClient.
This is the result of hacking a fix for multiline XPath in the SahiDriver
without touching the SahiClient, and then fixing it the right way later in
the client.
