Edit a plant that has an existing image in Cloudinary

[evabergold]

Hello,
I am currently working on the image upload to Cloudinary. This is my current pull request.

Uploading a new plant with an image works fine, also editing an existing plant and uploading a new image. However, one thing does not work: If I want to edit an existing plant, but only edit the name of the plant and not the image, I get the notification to upload a new file as the form only gets the preview image, but the input type file expects a file.

The image input has to be required because we use a placeholder image if the image is undefined (as a safety measure).

Currently we have only one form that is used for both creating and editing a plant. My idea to solve this issue would be to copy the entire form to create a new edit form and delete the image upload from the edit form, afterwards create a separate image edit form just for editing a plant's image.

Is this the best way to go or is there maybe an easier solution how to get the existing image to persist while editing other attributes of the plant?

Thanks!
