[PATCH] wininet: Clear cached credentials after the first failed attempt.

[Alistair Leslie-Hughes]

Windows when using cached credentials will use them on the first challenge,
if then a second 403 (ACCESS_DENIED) is received, the user is prompted again
but this time with the password and save checkbox cleared.
