Pluma: `org.mate.pluma color-scheme` is `unset`

[davidhedlund]

Description:

When switching between themes from the mate-themes and ubuntu-mate-themes packages, the background color in Pluma does not revert to its original state after switching back to the initial theme. Another text editor, gedit, is not affected.

Steps to Reproduce:

1. Open Pluma.
2. run

$ gsettings get org.mate.pluma color-scheme
'Yaru'

3. Change the theme to any mate-theme, for example BlueMenta. Pluma's is still white but the color-scheme is not changed, verified by:

$ gsettings get org.mate.pluma color-scheme
'Yaru'

4. Change the theme to any Yaru-dark. Pluma's is now set to dark background, verified by:

$ gsettings get org.mate.pluma color-scheme
'Yaru-dark'

7. Change back the theme to BlueMenta. The background color is still dark in Pluma, verified by:

$ gsettings get org.mate.pluma color-scheme
'Yaru-dark'

Observed Behavior:

• Themes from the ubuntu-mate-themes package configure Pluma’s color scheme by running gsettings set org.mate.pluma color-scheme '[STYLE]', where [STYLE] should be replaced with the name of any color scheme file (without the file extension) found in /usr/share/gtksourceview-2.0/styles/ for GTK-2 themes, /usr/share/gtksourceview-3.0/styles/ for GTK-3 themes, and so on. For example: gsettings set org.mate.pluma color-scheme 'Yaru'.
• The themes from the mate-themes package does not behave like this.

Expected Behavior:

• The themes from the mate-themes package should behave like the Observed Behavior for ubuntu-mate-themes
