test-client-custom-summary enhancements.

  o Added an invalid phone number to custom-6.vcf
  o Added a query test ensuring that E_CLIENT_ERROR_INVALID_QUERY is
    reported for a completely bogus query 'sexp' string.
  o Added a query test ensuring that E_CLIENT_ERROR_INVALID_QUERY is
    reported for a phone number query where an invalid phone number term
    is provided.
  o Added a query test ensuring that an invalid phone number string
    can still be matched using a normal E_BOOK_QUERY_BEGINS_WITH query
    on the E_CONTACT_TEL field (matching the invalid number in custom-6.vcf).
