serveronly: give the sub extension a way to access to the 'evolve' module

We keep it as clean as possible but if the extension is specified with a direct
path, we have to be a bit hacky.

Being able to access the whole evolve extension from the 'serveronly' extension
will lift multiple constraints on how we organise the code and will allow for
cleaner and clearer code.

We extract a minor function into a 'utility' module to have something to depends
on.
