[AtkinsChang]

Problem

vendor doesn't work with dependencies with different revs from same git. it should generate source replacement entry for each git revision.
The expected behavior is in the test case

Steps

test case

Possible Solution(s)

Use the SourceId url instead of git url for source name to avoid the source entry being overwritten. AtkinsChang@3a0fd08

ex.
[source."git+https://github.com/rust-lang/cargo?rev=6d6dd9d#6d6dd9d9be9c91390da620adf43581619c2fa90e"]
instead of
[source."https://github.com/rust-lang/cargo"]

Notes

If this solution is okay, I'll pr it.
