CLI errors when redirecting the output to a file

[Alexsander de Souza]

Using MAAS 3.3.0-beta2, when redirecting the CLI output to a file, we get this error:

$ maas admin machines read > test.list
usage: maas [-h] COMMAND ...

options:
  -h, --help show this help message and exit

drill down:
  COMMAND
    login Log in to a remote API, and remember its description and
                  credentials.
    logout Log out of a remote API, purging any stored credentials.
    list List remote APIs that have been logged-in to.
    refresh Refresh the API descriptions of all profiles.
    init Initialize controller.
    apikey Used to manage a user's API keys. Shows existing keys unless
                  --generate or --delete is passed.
    configauth Configure external authentication.
    config-tls Configure MAAS Region TLS.
    config-vault (placeholder) Configure MAAS Region Vault integration.
    createadmin Create a MAAS administrator account.
    changepassword
                  Change a MAAS user's password.
    admin Interact with http://10.10.0.31:5240/MAAS/api/2.0/

cannot use a string pattern on a bytes-like object

The location of the file doesn't change the results, even writing to /dev/null errors. Using a pipe (|) instead of redirection also errors. Calling the command without redirections work as expected.

It seems to work for the snap version (3.3.0~beta1-12847-g.2e1950694)
