Fix regression: missing eventHandlerTask.MODULE

A regression introduced removing `eventHandlerTask.MODULE`,
which was introduced in commit 00ae2f5 ("Decouple thread pool from event
handler"), but not removing the call to install that module, has been
corrected.

Fixes: ec1cf3b ("Bind GerritChange in event context")
