Fix jscodeshift import (fixes #1064)

[ohana54]

What kind of change does this PR introduce?
Fixes #1064

Did you add tests for your changes?
no :(
This requires testing the CLI itself (as the issue is in index.ts), and currently there are no such tests. I saw there are other CLI tests (for other commands), but none of them test a command which expects user input.
I found the inquirer-test package which might be helpful, so let me know how you think I should proceed here.

Summary
jscodeshift doesn't expose a default import, changed it to import the exported function correctly.

Does this PR introduce a breaking change?
no

LGTM
Just one thing! Did you make any changes with dependencies in your local setup or maybe version changes?
Not sure why those changes in the lock file came from!

[ohana54]

Well that's odd, I pushed this by mistake :(
I had no luck with this PR, multiple issues - I'll fix it right away.

lgtm thank you so much for your PR, and congratulations with your first one! 💙 This leads to a new error, can't Cannot read property 'push' of undefined at findPluginsByName.forEach (/webpack-cli/packages/migrate/uglifyJsPlugin/uglifyJsPlugin.js:68:41). Are you willing to fix this as well?

Open an issue using the example file provided in #1064, explain the issue and submit a PR afterwards!

Thank you so much ❤️

[ohana54]

Glad to help :)
Regarding the new error, I didn't get it in my use case, so didn't attempt to fix it.
I'll try to reproduce and fix as well.
