I see 2 main ways to support the queries logic for immediately executed tasks:
* DebuggableTaskRunner to return a collection of Runnable
* Create a separate instance of DebuggableTaskRunner for immediately executed
tasks, exposed by SEPWorker
I've selected the second way in the PR due to 2 reasons:
* the current virtual table schema assumes that DebuggableTaskRunner is only
the key in the table, so we cannot show several tasks at the same time with the
same id without changing the table schema
* changing of DebuggableTaskRunner API affects more classes
Nesting of immediate tasks is not supported intentionally, to avoid overheads
