aw: Add allow wait for form database

Follow up fix to refs/heads/master@{#463849}. FormDatabase is similar to
CookieManager. It's thread-safe singleton class that needs answers
synchronously from the database thread in the public webview API.

Missed this in the first round because there are no instrumentation
tests covering this, so add a smoke test.
