morph bug fix (#15370)

Two bug fixes here: 

# MorphRelationOneToManyFieldDisplay
we expect an empty array, not undefined (run time error otherwise)


Fixes `Cannot read properties of undefined (reading 'length'): Cannot
read properties of undefined (reading 'length')` in
**MorphRelationOneToManyFieldDisplay**

```js
morphValuesWithObjectNameSingular.every(
      (morphValueWithObjectNameSingular) =>
        morphValueWithObjectNameSingular.value.length === 0,
    );
```

# create record in table mode
if the record has a relation there is currenlty a bug in production when
it is created. A cache issue.

`Missing field 'companyFoundedId' while writing result `
