Describe the bug

I have a script file, which contains a bunch of commands like a root level def main and some def "main sub" etc. The script has an import of std log, i.e. a line containing import std log at the top. In my main definition, i have a --version flag, which if passed shows the version, else it shows the help command, this is what most of the in-built commands of nu does, that is show help command when no args are passed.
But this does not work. When no args is passed, i do help main, but instead of showing help message for the main command, it shows the help message of the imported log module from std log.
Running nu script.nu --help works fine, but doing nu script.nu which invokes help main in the script file does not work.

How to reproduce

Here's a reproducable script

use std log

# Root command
def main [
        --version(-v)
] {
        if $version {
                log info "printing version"
                print "version"
        }
        help main
}

# a subcommand
def "main sub" [
        --some-flag?: string
] {
        print "something to do here"
}

Expected behavior

Show help for the script file instead of showing help for the log module.

--help command works fine:

Does not work when no args are passed
