Fix resizing of TUI python windows

When resizing from a big to small terminal size, and you have a
TUI python window that would then be outside of the new size,
valgrind shows this error:

It's because tui_py_window::m_inner_window still has the outside
coordinates, and wnoutrefresh then does an out-of-bounds access.

Fix this by resetting m_inner_window on every resize, it will anyways
be recreated in the next rerender call.
