Title: Reflog refactor

The goal here is to make it easier to adapt to the mandatory-reflog changes in the native reference API.

Each logging call has been split in two: one which accepts both a log message and a signature, and one which accepts neither (and passes null for them to the first).

- [x] Split calls
- [ ] Cover new combinations with tests
- [ ] XML-docs
