Widgets: Implement TinyMCE on text widgets in Accessibility Mode

TinyMCE was not implemented on the accessibility mode for widgets, disabling text editing fields. Change ensures that TinyMCE is initialized when accessibility mode is set up. Prior implementation hid the text widget fields if they were empty, which they always were for new widgets.
