Issue description

Since 1.2.7 it is no longer possible to save an empty repeater.
Removing all items and saving, will result in no changes at all.
Removing 10 items, leaving one and saving, will result in one item in the repeater. Removing the last item will not work.

Steps to replicate

1. Create a repeater with content
2. Save
3. Remove the content
4. Save
   => The content is still there

Workaround

Delete the data through phpmyadmin/sql workbench/...

I figured when downgrading backend module to 1.2.6 it works again: "winter/wn-backend-module": "1.2.6"
(and Tailwind UI to dev-main#42dabcdf7e0daaa2b0dddd5fd5117412e8577e1a because latest version depends on Vite which was added in backend-module 1.2.7)

I think it is because of this
wintercms/wn-backend-module@9cc2bd8

But reverting this also seems to break the repeater (all empty repeaters get an empty row)
@LukeTowers any idea?

@AIC-BV is this still an issue on the latest develop branch? @mjauvin any thoughts?

@AIC-BV can you test #1300 and let me know if that solves the issue?
