Fix/image inputs

[chrismclarke]

Done

• Add support for ImageInput to take a generic value property instead of just a preview string (tidies the handling of multiple inputs away from components using the input to the input itself, and makes it possible to do more with the full input meta)
• Bind ImageInputField to direclty pass value from form (removes need for manual methods)
• Remove canDelete and replaceImage prop (assume images can always be deleted in edit mode so better to calculate from whether images are present, image replacement nice but not really necessary as user can just delete and then upload a new one)
• Cherry-picked a few of the fixes from Refactor - CI Backend (+db prefixes) #952 to try and get tests passing
• Add up arrow as hotfix for howto step arrow display

Todo

• Now that full upload image meta available we should add a method to delete image from server on image delete (included as inline todo comment, but could be made higher priority?)
• Not likely required at this point as we don't have anything using multiple image uploads, but if we ever do would probably want to add a different method to display. At the same time we could refactor current forms to use a single multiple image upload field instead of multiple individual ones (v. low priority).
• After Refactor - CI Backend (+db prefixes) #952 approval will need to resolve conflicts created here and uncomment broken howto image check.

Nice refacto !
No problem with this code so I'm approving.
One thing to note though is that I fall on bug #781 while trying to upload cover image, I had to change it to make the upload works.
See my comment in issue for potential fix.
