Add a basic test for add-report in `storage.clj`
Add a basic test for add-report in `storage.clj`

Prior to this commit I didn't have any tests for
`add-report!` in `storage.clj`.  This commit adds
a basic test.  We could probably use some additional
tests there, but this will at least serve as a
placeholder.
