Test reliability: suggestedActions.js "should show response from bot and text from user on messageback"

Feature Request

This is due to race conditions from Direct Line channel.

FAIL __tests__/suggestedActions.js (92.842s)
  ● suggested-actions command › should show response from bot and text from user on messageback

    Expected image to match or be a close match to snapshot but was 1.745659722222222% different from snapshot (4022 differing pixels).

[Enhancement]

The failure is in tests/suggestedActions.js at the messageback snapshot assertion on line 149; start by running that test and tracing its Direct Line message timing. Done means the test reliably captures the expected state and passes with the expected image snapshot.
