Do not fabricate scheduled basals

Also, do not update the schedule based on basals that we have seen.

This change implements both of these things, but there is still a case where we need to fabricate scheduled basals and that is when a temp percent is active.  This change does not implement that yet, but it has adjusted the tests (specifically withoutSettingsChanges) to expect that.  So what's left is to make that test pass.
And the tests now pass!
Add an annotation for basals generated under a carelink temp
Manage timestamp on settings properly

We maintain the earliest timestamp seen in the data for a given upload so that we can set that on the settings object when we are done processing the data for that upload.
