Hi,

When attachments: false on a rich_textarea: <%= form.rich_textarea :content, attachments: false %> we get these behaviours:

• No images appear in the editor on upload
• Drag and drop is disabled
• Pasting images is disabled
• Dev console to warn: This editor does not support attachments (it's configured with [attachments=false])

From that I would also assume the upload icon should not show up as well

Actual behaviour:
The image button on the toolbar is displayed.

Expected behaviour:
The image button on the toolbar is removed.

Happy to provide a PR if this is considered a bug, and contributions are welcome.
