[Filament\Tables\Testing\TestsBulkActions::mountTableBulkAction()](https://github.com/filamentphp/filament/blob/f8d751acb8527abda6abe6f9ee1106dd706a8171/packages/tables/src/Testing/TestsBulkActions.php#L46), $this->instance() is returning null and causing it to crash.$this-instance() works fine in previous method calls on the Livewire Testable instance but not in this method for some reason.

Livewire::setUpdateRoute() then my tests pass. It looks like the Livewire update was failing due to routing issues and then the next component state was null. For now I'll just only modify the update route when not running unit tests and this should work fine for now.
