Looks like this change broke API tests on iOS

        Expected: "PersistentCookieName=CookieValue; SessionCookieName=CookieValue"

Reverted r234517 for reason:

Caused API test failures on iOS

Committed r234561: <https://trac.webkit.org/changeset/234561>

The test is failing because: for an existing processPool, registerForNewProcessPoolNotifications won't be called, so we don't do flushCookieStore and persistent cookies are not written to file for synchronization.

We could do a workaround fix for this, but since we are going to do a complete fix by always launching network process whenever needed, and this bug seems to have little impact now. I think we could hold it for later.
