Query `client` with `sexp`, receiving a list of contacts which matched. If successful, then the `contacts` is set to newly allocated GSList of EContact-s, which should be freed with `e_client_util_free_object_slist()`.

Note: `sexp` can be obtained through EBookQuery, by converting it to a string with `e_book_query_to_string()`.

`client` : | an EBookClient
`sexp` : | an S-expression representing the query
`contacts` : | a GSList of matched EContact-s. [element-type EContact][out]
`cancellable` : | a GCancellable; can be `NULL`
`error` : | a GError to set an error, if any. [out]
Returns : | `TRUE` if successful, `FALSE` otherwise.
