[RTDB Emulator] Disabling strictTriggerValidation doesn't work like actual RTDB

### [REQUIRED] Environment info

**firebase-tools:** v9.16.0
**Platform:** macOS
**`firebase setup:emulators:database`:** firebase-database-emulator-v4.7.2.jar

### [REQUIRED] Test case

Disable [`strictTriggerValidation`](https://firebase.google.com/docs/database/usage/limits#global).

Create a function listening at a RTDB path (e.g. `/users/{userId}`) and then using the Admin SDK write 1001 records.

This fails against the emulator but fine against a live RTDB instance.

### [REQUIRED] Steps to reproduce

As above.

### [REQUIRED] Expected behavior

`strictTriggerValidation` to be disabled and the write allowed.

### [REQUIRED] Actual behavior

`TOO_MANY_TRIGGERS: This request would cause too many functions to be triggered.` error.
