Some crates counted multiple times for the final tally

[Shnatsel]

If a crate occurs multiple times in build dependencies, the number of unsafe blocks in it seems to be added multiple times to the final tally.

For example, release 0.11.3 of https://github.com/algesten/ureq totals 2574 unsafe expressions according to cargo-geiger 0.9.0, but that number doesn't align with the individual crate counts. It seems that ring with its 480 unsafe expressions is counted multiple times, otherwise there's no way to explain these results.

Thank you for the report! I will try to find some open source time in the coming weeks.
