Hide empty log groups in the task log view - #75686

The task runner always opens a "Post Execute" log group after execute() returns, but for a plain task nothing is logged at INFO before it is closed, so the UI showed a section header that expanded to nothing. When parsing logs, drop a group header if the group closes with no entries in it. A parent containing only empty groups is dropped too. Unclosed groups are kept so a running task still shows its current section.
