[PATCH 1/2] shell32/tests: Wait for window to close in check_window_exists

[Alex Henrie]

This fixes a race condition where the directory is deleted before the
window closes, which causes an error dialog to appear.

Cutting the number of iterations per wait loop in half is necessary so
that doubling the number of wait loops does not result in a timeout when
new tests are added.
