Content: Cannot Create a New Item Once a Field's API ID is updated

[zcolah]

Describe the bug

1. I cannot create an item, if I update the Field API ID. Please see Loom for more context: https://www.loom.com/share/11760952f69f4db485541a4c90b44beb
2. Here is another Loom showing how I am stuck and unable to get out of the bad state: https://www.loom.com/share/ffeb4d62564c432bb36bb767fadfee6c?from_recorder=1&focus_title=1
3. Create Content Item Page: https://8-da92b5d8e6-hvp4w4.manager.zesty.io/content/6-8ed3fbd5fb-5n4cvt/new
4. Model: https://8-da92b5d8e6-hvp4w4.manager.zesty.io/schema/6-8ed3fbd5fb-5n4cvt/fields

@agalin920 could this be due to the model fields not being refreshing in local cache when a field item is changed?

Please provide replication steps

[agalin920]

Reproduction steps.

1. create a new multi page content item
2. do not save it and leave as 'draft'
3. edit its respective model
4. go back to the unsaved draft (that is saved in local memory)
5. Draft was created using old model so it fails upon creation

This edge case relates to the fact that upon creating a content item it is 'drafted' in local storage with the model as the template. When editing a model and coming back to the draft, the draft still has key:value pairs pertaining to the old model

Solution:

Remove key:value pairs that are no longer present in the model
