Unsetting of variables does not work

[mgrottenthaler]

According to the documentation you can unset a variable by typing set variable-name "":

set variable-name new-value (a value of "" will clear the variable contents),

This does not work in the current version. I get the following error message:

» set events.stream.output ""
» [16:00:51] [sys.log] [err] unknown or invalid syntax "set events.stream.output", type help for the help menu.

Environment

• Bettercap version: 2.11
• Kali Linux Rolling
• Command line arguments: bettercap -iface eth1
• Full debug output: [sys.log] [err] unknown or invalid syntax "set events.stream.output", type help for the help menu.

Steps to Reproduce

1. type: set events.stream.output ""

Expected behavior: The variable is unset/set to an empty string

Actual behavior: Error!

Although an empty value is a defined value, a new command like unset could undefine environment variables.
