  Description

This PR fixes the labelOnInput by treating the following points that were making broken and unhelpful:

• it doesn't check textarea and select
• it whitelists the input types instead of excluding those that don't need a label
• labels for attributes always returns undefined it should be entry.attributes.for.value
• the offending array is not filled with the id or name of the offending inputs
