When a repo contains a `rust-toolchain` file, Travis’ build matrix does not install the requested rust version, and always uses the version defined in the `rust-toolchain` file instead.

Is there a hook I could use (`before_install` or strh like that) to remove the `rust-toolchain` file from the CI workspace before the toolchain installation? Or, maybe there’s other workaround for this issue?
