Revert "Persist cookies for profiles with non-null path"

This reverts commit 6cd69069.

Reason for revert: broke weblayer instrumentation tests, see https://ci.chromium.org/p/chromium/builders/ci/Mojo%20Android/20184?blamelist=1#blamelist-tab

Original change's description:
> Persist cookies for profiles with non-null path
>
> Currently the cookies are not persisted because the default
> implementation of ContentBrowserClient::CreateNetworkContext doesn't
> specify cookie_path parameter. In this CL CreateNetworkContext is
> overridden in WebLayer implementation.
>
> Bug: 1014048
