rbw gen-completions ${shell} fails for debug build

[antecrescent]

A Gentoo Linux user reported this here: https://bugs.gentoo.org/935517

To reproduce, build rbw with the debug profile (i.e. don't pass --release to cargo build) and run the following:

RUST_BACKTRACE=1 /var/tmp/portage/app-admin/rbw-1.12.0/work/rbw-1.12.0/target/debug/rbw gen-completions bash

This seems to fix it, but don't understand yet why it does or if that's the correct fix. The issue could be related to clap-rs/clap#2475.
