This makes sure 'self' comes first. While at that fix the
function signatures and use ServerContextService directly
and add type checks so it's easy to notice when we messed up.

It's confusing when the object a method acts on is sometimes called
context and sometimes called state. So name it 'self' as we do
in other projects.

There's no point having it for a final type and it only
makes the code harder to read.

The previous commits show it's not really a derivable type
so make it a finale one.

It's unused

G_DECLARE_FINAL_TYPE does this for us

No changes needed.
