The String implicit casting is resolving a string Literal to an UnresolvedAttribute if the conversion fails and it's, also, adding a specific error message. But, later in the resolving process this message is lost when ES|QL tries to find field names suggestions. This PR stops the resolution if there is already an UnresolvedAttribute with a specific error message (like the one coming from implicit casting resolution).
