Patrick Steinhardt 1e7e4a111f environment: stop storing "core.notesRef" globally
Stop storing the "core.notesRef" config value globally. Instead,
retrieve the value in `default_notes_ref()`. The code is never called in
a hot loop anyway, so doing this on every invocation should be perfectly
fine.

* decide on whether or not we have a `struct repository`.
*
