Give manual activity tests time for the start handshake

test_manual_heartbeat and its siblings start a standalone activity with a
5s start-to-close timeout, then wait for the activity to report that it
started through an EventWorkflow before completing, cancelling, failing or
heartbeating it by ID. That handshake includes the first workflow task of a
cold worker, which on a loaded macOS runner took over 5s; the attempt timed
out and the heartbeat failed with RPCError NOT_FOUND ("activity not found
for ID"). Nothing in these tests depends on the attempt timing out, so give
the attempt a minute.
