Fix use -h to call cmd_use_help

[wvu]

It really shouldn't try to load it as a module.

• Test help use
• Test use with no arguments
• Test use -h
• Test use with a module

msf5 > use -h
[-] Failed to load module: -h
msf5 >

msf5 > use -h
Usage: use module_name

The use command is used to interact with a module of a given name.
