gsettings: Support per-desktop overrides in GSettingsAction
Due to an oversight (I guess), per-desktop default values (which come
from override files such as this one:
https://github.com/endlessm/gnome-shell/blob/master/data/00_org.gnome.shell.gschema.override)
were not checked when getting a GSettings value via a GSettingsAction
.
Per-desktop default values are correctly returned via all other
GSettings query paths (see calls to
g_settings_schema_key_get_translated_default()
).
