Move all EE differences to EE directory

1. Create a CE counterpart for noteFormMixin
2. Use ee_else_ce to import the mixin into this file.
3. Move the differences in handleKeySubmit & handleUpdate to the mixin
4. Wrap the template differences with a v-if for renderIfEE and move it
to CE.
5. Guarantee that specs exist or are added
