When the cannula tubing is primed on Medtronic pumps (manual prime), the history entry that gets logged is the same type as a fixed-prime (for priming the cannula after it has been inserted) so any time the reservoir was replaced AAPS would log a site change which reset autosens unnecessarily and also led to inaccurate reporting of insulin/cannula changes in Nightscout.
This commit aims to fix that by checking the `FixedAmount` data entry of `Prime` history entries to detect whether the prime was a manual-prime (priming tubing) or fixed-prime (priming cannula) and skip logging a site change event if it is the former. In order to automatically log insulin reservoir replacements, this commit also adds a monitor for `Rewind` history entries which logs an `InsulinChange` event for them (similar to the priming monitor).
