[Bug] Disabling entry filters isn't possible when allowOverrideEntryFilters=true and entryFilterNames is specified in broker.conf

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Version

3.0.x, master

### Minimal reproduce step

Disabling entry filters isn't possible when `allowOverrideEntryFilters=true` and `entryFilterNames` is specified in `broker.conf`.

### What did you expect to see?

It should be possible to disable entry filters completely at topic level when `allowOverrideEntryFilters=true`

### What did you see instead?

The `entryFilterNames` in `broker.conf` are used when the list of entry filters for the topic is empty. Please see the code:
