‐Fix for #5678 …snackbar reappears…

Thanks for the tip, a bit advanced for me but I got it to work after some puzzling.

I've also tested with a dummyFailedValidationResult.

And thanks @ln for the kind welcome, it's nice to be back.

Closes #5678?

What has been done to verify that this works as intended?

Tested manually.

Why is this the best possible solution? Were any other approaches considered?

Seems to be "the simplest thing that could possibly work". More elegant alternatives could be to change the signature of FormEntryViewModel.getValidationResult to reflect the actual class; or completely encapsulate with something like resetValidationResult.

How does this change affect users? Describe intentional changes to behavior and behavior that could have accidentally been affected by code changes. In other words, what are the regression risks?

Behaviour is now as expected. Doesn't break any tests.
