Fix google-places losing already-fetched leads on a mid-pagination failure

search() accumulated results across up to 3 pages in a local array, but a
failure on page 2 or 3 (e.g. Google's next_page_token not active yet
despite the 2.5s wait, or a transient error) propagated out and lost the
whole accumulated array, not just the failing page. The caller's catch
only logs and continues, discarding leads that were already successfully
fetched. Now only rethrows (preserving existing behavior) when nothing has
been accumulated yet; a failure after at least one successful page logs
and returns what was already collected.

Found via a full-project audit.
