Bug: Synchronized TVs never triggered

[arjen-t]

When defining synchronized TVs (comma-separated list of TV IDs), this never triggers the sync procedure.

The reason lies in the following line of code, line 290 in the Babel class.

babel/core/components/babel/src/Babel.php

Lines 288 to 294 in 61c0dfc

	/* synchronize the TVs of linked resources */
	$syncTvs = $this->getOption('syncTvs');
	if (empty($syncTvs) || !is_array($syncTvs)) {
	/* there are no TVs to synchronize */
	return;
	}

The $syncTvs is retrieved from the setting on line 289. But the setting always returns a string, empty or comma-separated TV IDs. This causes the syncing never happens because it isnt an array.
