fix(ui): safely accesses field in default filter component (#9276)

### What?
In the WhereBuilder Condition DefaultFilter component, there is a switch
statement that contains components to return based on the built filter
in the admin ui. Having a filter built out then navigating to another
collection list view causes an error to occur due to InternalField being
undefined but the DefaultFilter tries to access the field on it.

### Why?
To fix unexpected `cannot access property field of undefined` errors.

### How?
Adding a conditional chaining operator.

Odd thing here is that the `Text` component where this error originates
from doesn't actually make use of the passed `InternalField`. Might be
worth it to take a closer look at it.

Fixes #9179
