[seahorse/gnome-3-30] Use string.data to convert a string to a uint8[]

[Niels De Graef <nielsdg src gnome org>]

commit 07120b25e6db010c7449764ffe147c3c23404343
Author: Niels De Graef <nielsdegraef gmail com>

    Use string.data to convert a string to a uint8[]
    
    Otherwise, vala will pass on an array length of -1, which can crash in
    some cases (such as `Bytes.new()`).
    
    Fixes https://gitlab.gnome.org/GNOME/seahorse/issues/206.
