Improve the error management for Poll

[fabien0102]

Why

Because as a noob I've commited a .skip on this part 😆 and also because we have a lot of foggy spots on this part.

The idea is to be as close as possible of Get regarding the comportement and also continue polling after an error (so the until props is really useful)

You've got to be kidding me. I should have caught this in the review!

Using yarn as the package manager for this project is a real problem. Our .prettierrcs are not synced because of yarnpkg/yarn#5476, since the postinstall from https://github.com/contiamo/operational-scripts doesn't execute. :(

We should either:

• a) drop yarn and use npm,
  • This means a large commit of changing lockfiles
• b) fix it on yarn
• c) npm install @operational/scripts and then remove package-lock.json.

I added a commit here that formats everything correctly since your initial commit added some formatting already.

From this point on, I don't think we should have any more formatting discrepancies in diffs.
