Running the `console` and `dbconsole` commands with a regular argument
as the environment's name automatically expand it to match an existing
environment (e.g. dev for development).
This feature wasn't available using the `--environment` (a.k.a `-e`)
option.
People should rather rely on the `-e` or `--environment` options to
specify in which environment they want to work. This will allow us
to specify the connection to pick as a regular argument in the future.
