bump clone-deep dependency

[mmkal]

I'm using a package which uses merge-deep, which I'm then trying to webpack. So opening this PR to bump the clone-deep dependency to get the fix (from 2015!): https://github.com/jonschlinkert/clone-deep/commit/2d977fcd063a68981588d637e9f2e2157ad66f87

Hopefully CI will tell me if this blows up.

Hi @mmkal and @gastonfournier

We just had issues with this at work and fixed it with package json resolutions

Just add this in package.json

"resolutions": {
    "clone-deep": "^4.0.1"
  }

Think this is the best we get as the project looks abandoned.
