use $0.00 for price if price not defined, log info

Price can be undefined, CT does not require price on products. This currently crashes product import.

Hi @KthProg,

Thank you for the contribution. We currently work with Klaviyo maintaining this integration, at this time the way we handle PRs is by committing/reviewing changes internally (in a private repository) and then syncing those changes to this repo (see here for a previous instance of this).

We've already been notified by Klaviyo, so we'll take a look at this internally to get it merged (and ideally make it available in Connect) and we'll let you know when it's done. Thanks!

[KthProg]

Awesome thank you very much. It may be a good idea to put that info on the contribution document?

Right now it just says to open a PR.

[andreshernandez-e2x]

We've merged your change and synced it to this repository, we're currently just waiting for commercetools to certify the Connect release.

Also, thanks for mentioning the contribution document. We've updated it reflect the current way of working for any future contributors.

[andreshernandez-e2x]

The latest version has been certified by commercetools and should be available now in Connect. With this changes have been completed, so I'll be closing this PR.

Thanks again for your contribution!
