./miri bench is broken, tries to run cargo + miri run

[saethlin]

    Replaced package `cargo-miri v0.1.0 (/home/ben/miri/cargo-miri)` with `cargo-miri v0.1.0 (/home/ben/miri/cargo-miri)` (executable `cargo-miri`)
Benchmark 1: cargo + miri run --manifest-path /home/ben/miri/bench-cargo-miri/backtraces/Cargo.toml
Error: Command terminated with non-zero exit code: 101. Use the '-i'/'--ignore-failure' option if you want to ignore this. Alternatively, use the '--show-output' option to debug what went wrong.

I truly have no idea why this is happening. There hasn't been a recent hyperfine release.

Ah I screwed up when reordering some things in ./miri...
