v0.18.7 - Revert to v0.18.3 answer processing logic

Reverted pollInternal to exactly match v0.18.3 which was the last
working version. The changes in v0.18.5 and v0.18.6 that moved the
answered flag and timestamp updates were causing issues.

v0.18.3 working logic restored:
- Check !activeOffer.answered
- Call setRemoteDescription (no try/catch)
- Set answered = true AFTER
- Update lastPollTimestamp AFTER
- No pre-emptive timestamp updates

The only difference from v0.18.3 is the eventemitter3 import which
should not affect answer processing behavior.
