LDAP registry and URBridge are not un-escaping double quotation and apostrophes from the XPATH search expression

[jvanhill]

When a WIM search operation with a search expression that includes escaped apostrophes or escaped quotation marks, the LDAP registry and UR bridge (which calls UserRegistries such as Basic Registry and custom UserRegistries) are not un-escaping the escaped characters in the XPath expression. This can lead to expressions that result in incorrect search results.

For example the search expression:

@xsi:type='Group' and (cn = "*""*")

may result in the LDAP search filter:

((&objectclass=groupofnames)(cn=*""*))

and/or the UserRegistry search expression:

*""*

Note that these errors can only be encountered when doing searches with the 'filter' parameter for SCIM searches.
