fix(polls): you can vote on a poll you just created (#284)

PollContent read mEvent.getId() once at render. For your own new poll
that is the local echo id (~!room:txn), and nothing re-rendered it when
the SDK swapped in the real $id, so the vote related to the local id
and the SDK threw synchronously (getPendingEvents under chronological
ordering): no vote was ever sent. Track the id via LocalEventIdReplaced
and Status, block voting while it is still local, and catch synchronous
throws. Adds the Playwright regression the issue asks for.

Fixes #284
