Issue 2329 logfile 1 (#2344)

## Description

Prevents showing the log file location when calling commands that defer to help output or env details.
Certain cases aren't caught, such as when calling a command with no flags (ex: `corso backup create exchange`).
In those cases we catch the lack of flags and manually display the usage within the command handler.
