[8.x] Fixed config batching typo

[garbetjie]

Ensures the config key used for determining the table name in queue:batches-table console command is the same as the config key used when registering batch services in

framework/src/Illuminate/Bus/BusServiceProvider.php

Lines 49 to 50 in 4063a57

	$app->make('db')->connection(config('queue.batching.database')),
	config('queue.batching.table', 'job_batches'),

Currently, the console command uses queue.batches.table, and when registering batch services queue.batching.table is used.
