cleanup worker task logging

In order to avoid name conflicts with WorkerTaskContext

- renamed WorkerTask::log to WorkerTask::log_message

Note: Methods have different fuction signatures

Also renamed WorkerTask::warn to WorkerTask::log_warning for
consistency reasons.

Use the task_log!() and task_warn!() macros more often.
