Run: Change log level for recipe init error

[JohanLorenzo]

I ran into these logs:

I didn't immediately notice that there was an error hidden in there. Here's a small patch to prevent that from happening again.

I'd prefer if it were a warn rather than an error, but wfm.

[JohanLorenzo]

I think that's technically an error: the operation requested (aka "create a new rule") failed, I wasn't able to see it in the UI. A warn is more appropriated when the operation recovered and managed to create the rule anyway (like with a default value).

What do you think @Yoric ?

[Yoric]

Well, it's a user error, rather than a foxbox error, and I think that we need to make a difference between both. A custom macro would probably be useful. In the meantime, I'd say that it's a warn, but I'm not going to insist strongly.

[JohanLorenzo]

My bad, I didn't realize it's a user error. I changed it to warn
