[BUG] Changing 'Field Type' doesn't invalidate cache in JsonGenerator

[TobyDS]

Has this bug been raised before?

• I have checked "open" AND "closed" issues and this is not a duplicate

Description

When changing the field type after having clicked on preview or export does not cause a cache invalidation. This results in Json being given to the user which does not conform to their specification when clicking on preview/export again.

Steps to Reproduce

Include any relevant details like:

• Go to JsonGenerator
• Set the field names and their types
• Open preview or click export.
• Change one of the types without adding or removing a field, or changing the field name.
• Click on preview or export again and observe the incorrect Json being provided

Do you want to work on this issue?

Yes

If "yes" to above, please explain how you would technically implement this

Update the cache checking function in utils.js to take into account a change in field type, not just field name
