neo-cli No Screen Rendering on Invalid Arguments.

[cschuchardt88]

Describe the bug
when you type invalid arguments on the commandline for neo-cli.exe. You get an error message; however, the CLI prompt still opens; allowing you to enter commands. When you enter command show state; this ends up not rendering the screen and also clears the screen.

The reason i think it is doing this is because of the command text coloring that, causes the show state method to not render correctly.

To Reproduce
Steps to reproduce the behavior:

1. Type command neo-cli /noverify in powershell
2. Type show state in the neo-cli prompt

Expected behavior
If there is invalid arguments passed in. Than there should be no neo-cli command prompt or the arguments should be ignored.

Screenshots

Platform:

• Version neo-cli 3.6.3
