cc: Remove impl_transform_is_unknown argument from OcclusionTracker.

This argument is just used for an early out. Instead don't call the
method at all when it is true.

Avoid a CHECK in ExtensionActionStorageManager::ReadFromStorage if an extension
has a browser action which it starts reading from storage on startup, but then
it's updated to a new version with no browser action before the callback comes
back.

A better way to fix it would be to block the update until the extension is
"started", but we need better infrastructure to do that.
