Mutter 51 has removed the experimental-features key in the org.gnome.mutter schema (and introduced a new org.gnome.mutter.experimental schema, but that doesn't matter here).
Additionally, some settings, such as fractional scaling, are on by default and no longer experimental.
We should handle these gracefully so tilingshell works across multiple versions
