515: Fix error propagating logic r=ellnix a=ellnix # Pull Request ## Related issue Fixes #513 ## What does this PR do? - Meilisearch::ApiError parses a server's JSON response into its ``@http_body`` instance variable which stores a hash. - When `version_error_handler` propagates `ApiError`, it passes the ``@http_body`` hash as http body which causes `ApiError` to attempt to parse it again as JSON, throwing a `TypeError`. - This PR makes the `http_body` parameter polymorphic, allowing either a hash or a JSON string to be passed.
