This change improves the loading of reviews in two ways:
Do not return a nil error from getSummaryFromNotes if the returned
summary is nil, as that breaks assumptions made by callers that one
of the two return values must be non-nil.
Proactively check that the specified hash exists and points to a commit
object before trying to load a review attached to that commit.
The combination of these two changes fixes #73
The first change prevents the tool from panicing on a bad input, while
the second change makes the error message presented to the user easier
to understand and fix.
