Subject: krb: recreate ccache if it was deleted


https://fedorahosted.org/sssd/ticket/1512

If directory where a ccache file was stored was missing and user
was still logged in, we erroneously considered the ccache file
still active. Thus the ccache file was not recreated and user was
unable to login.
