Description Ryosuke Niwa 2018-02-22 23:25:26 PST 
After https://trac.webkit.org/changeset/228589, some people are hitting release assertions.
There appears to be a race condition between UI process and WebContent process's preferences being synced vs web view being created.

The work done here seems harmless so maybe we can do it anyway, especially since we are disabling any IPC to Messages::WebSWServerToContextConnection?
I am not familiar with this routine but maybe there is a chance for a race condition somehow so that we initialize the website data store first and get the entitlement later on.

We need this check to disable service worker in the storage process.
