Tracing was changed and no longer deliver events in right order. Parent
event is closed after children event and this is the order tracing event
appear. This CL pre-sorts events based on timestamp and duration to make
sure parent event goes first. This additionally fixes crashes in error
logging and removes bottleneck in building common tracing model.

TEST=Manually + unit test. Observed that common model is built in less
than second, compared with ~ min (debug unit test) with old approach.
