WP-CLI overrides default WP password when no password is set

[tomsommer]

WP-CLI tries to set a default password outside of WordPress Core's functionality

core-command/src/Core_Command.php

Line 623 in db88c14

? wp_generate_password( 18 )

This is not smart, because it prevents WP from sending the auto-generated password in the welcome-mail.

If --admin_password="" is provided, it should be honored and passed to Core as such, WordPress it-self will generate a random password.

This sounds reasonable to me.
