iOS: Always call setParent during QIOSWindow construction

Browse Source 
We rely on setParent for parenting top level windows into our desktop
manager view, so we can't condition the call on having a parent window,
like we do on other platforms.

This was a regression from 988039729f55a5e62e32b82c6f29ff7457e91d9d.
