wininet: Set file size in container object to avoid closing/reopening index on every lock index operation.

[Morten Rønne]

This is a internal wine problem, which doesn't affect any tests.

If you want to see the problem in action, comment the assignment and 
change the added TRACE to a FIXME, and run tests.
Then do the tests again with the assignment added and see the difference.

Best Regards

Morten Rønne
