doesn't support scrolling through older commands

[Delta456]

Describe the bug
I cannot scroll through the older commands used by me

To Reproduce

• Type one command
• Type another command
• Try accessing the previous command or older ones by using keys

Expected behavior
To be able to see all previous commands used, like in zsh:

Environment

• OS: Pop OS
• Output of inshellisense --version: 0.0.1-rc.1
• Nodejs Version: 9.8.1

Additional context
Add any other context about the problem here.

There's inshellisense --history which stores the last used commands, perhaps take inspiration from there?

Duplicate of #9, but for zsh

Closing as this was fixed in 0.0.1-rc.5
