[gvfs/wip/hadess/fast-content-type: 9/10] smb: Don't set a content-type that isn't certain

[Bastien Nocera <hadess src gnome org>]

commit 4316e25258bfe45cad891e200721fe50d244da0d
Author: Bastien Nocera <hadess hadess net>

    smb: Don't set a content-type that isn't certain
    
    Don't ignore the result_uncertain flag from g_content_type_guess() as it
    might cause nautilus to incorrectly think that a particular file is of a
    certain type, and never check its magic.
