Re-landing "Add disable WebRTC encryption tests".

Original CL https://codereview.chromium.org/170623003:
"- Broke out copying of the disable encryption command line flag to its own function. Added unit test for it.
- Added browser test."

This new CL fixes failing MANUAL_TestVGAVideoQuality.

Start reconcile if tokens are available.

The acount reconcilor makes a supposition that ProfileOAuth2TokenService
send OnRefreshTokenAvailable notifications after the account reconcilor
is initialized.

On iOS this is not the case: the ProfileOAuth2TokenService loads its
accounts and send OnRefreshTokenAvailable notifications before the
account reconcilor has the time to listen for these notifications.

This means that the accounts may not be reconciled when the app starts
Chrome.

BUG=NONE
