Subject: [PATCH] backend/rest: check HTTP error response for List

Before this change restic would attempt to JSON decode the error
message resulting in confusing `Decode: invalid character 'B' looking
for beginning of value` messages.  Afterwards it will return `List
failed, server response: 400 Bad Request (400)`
