[worker] - Stop sending already-caught exceptions to sentry. Log them instead

[heysamtexas]

We already catch webdriver exceptions and handle them. Sending them into sentry does nothing but confuse things.

This is a misuse of sentry. We should simply log these handled cases somewhere. Either log it as STDERR / STDOUT or just stick it in a database table and we can look at it later.

This also affects webhooks. The webhook should send back a status and the error message to the service that called it.
