[stable] Remove bad assert from socket profiling stat collection
Issue description: When users click 'Clear' in the DevTools Network
screen, they can see many assertion errors in the app console.
What is the fix: The assertion is erroneous, and is removed.
Why cherry-pick: The errors and stack traces are very disturbing to users.
Risk: Low, this fix has landed on the main channel and is tested on the same infrastructure.
