Automated rollback of commit 247bd0d1cac9f436ba1d32e9b9bdbc5bd212691f.

*** Reason for rollback ***

Deadlock in `recordTask` function

*** Original change description ***

Fix compare and update race condition in Profiler.

In rare cases when the action finishes lately we could compare TimeSeries to null, and then during assigning get null value.
