fix: compile errors on Arch for forward declared class

`TreelandConfig` became a forward declaration on
fa1e1e6a18 which breaks moc compilation on
Arch with the following errors. Let's use `Q_MOC_INCLUDE` like the
others to workaround it. Note that `Q_DECLARE_OPAQUE_POINTER` should be
avoided here because `TreelandConfig` is a `Q_OBJECT`.
