[4.0] xtd-editor fields plugin

[brianteeman]

While testing #32585 I couldnt understand why my editor didnt display a fields button. It turns out the reason was that if there are no fields the button is never displayed. While I understand the logic behind that it is inconsistent with other xtd-editor plugins such as contacts or modules which do not check to see if records exist before rendering the button.

Looking at the code it appears to be something a bit more complex and that the intention was not to display the observed behavior but is a side effect of a check to ensure the fields for the correct component are displayed.

	// Validate context.
	$context = implode('.', FieldsHelper::extract($context));
	if (!FieldsHelper::getFields($context))
	{
	return;
	}
