`forc-wallet account` command panics

[tritao]

As the example below shows, when issuing a forc-wallet account command, a panic is given.

Ideally this would be changed to something a little bit more friendly.

~/dev/forc-wallet$ cargo run --bin forc-wallet -- account
    Blocking waiting for file lock on build directory
    Finished dev [unoptimized + debuginfo] target(s) in 8.67s
     Running `target/debug/forc-wallet account`
thread 'main' panicked at 'failed to invoke `forc wallet account --help` command: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/account.rs:310:10
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I can't seem to repro this - what version of the wallet is this on?

I'm on: commit cdf3a933a6af1eaeead2966da7151c4590cf961a (HEAD -> master, tag: v0.2.2, origin/master, origin/HEAD)

Here is a full trace in case it helps:
