WebDriver: Rename Session::{get_window_object => current_window}()

- It's not a "window object" (in the JS sense), it's a simple struct
  storing a handle and is_open property
- We usually omit 'get' for getters
- The new name makes it more clear that this is looked up using the
  m_current_window_handle as a key
