[shotwell] SSL: Make it more clear that something failed

[Jens Georg <jensgeorg src gnome org>]

commit 932c069ee35dff32d92b0a1ff04273210c77f684
Author: Jens Georg <mail jensge org>
Date:   Fri Aug 12 12:05:43 2016 +0200

    SSL: Make it more clear that something failed
    
    First step of improved SSL communication. Make it more clear that something
    unrecoverably failed with SSL instead of just re-displaying the auth page.
