Title: Calling Form->input() with 'error'=>'' should trigger field error, but not render error element.

The idea is to complete [1] and [2] which enabled to trigger element errors (field coloring) but not rendering error messages.

Actually, calling ```Form->input()``` with:
```'error' => false``` prevent any kind of error reporting (field error coloring _and_ error messages)
```'error' => ''``` allow field error coloring _and_ render an HTML element with and empty error message

IMO,
```'error' => ''``` should allow field error coloring _but_ prevent rendering an HTML element with and empty error message.
