Describe the bug

We noticed that starting from 3.13 the license activation for fresh installations are not working in some cases, so the licence-data.php is removed and the license is validated in the first time but then when opening the settings page we see the license validation page which has empty fields.

After digging into this I found that the license is validated at first successfully and then when dynamic lists are grabbed from our backend API and saved, we try to save the options again but seems like this is getting our settings option as empty array so the license details are removed from our options.

wp-rocket/inc/Engine/Optimization/DelayJS/Admin/SiteList.php

Lines 290 to 299 in d95ff93

	public function refresh_exclusions_option() {
	$selected_items = $this->options->get( 'delay_js_exclusions_selected', [] );
	$this->options->set(
	'delay_js_exclusions_selected_exclusions',
	$this->get_delayjs_items_exclusions( $selected_items )
	);
	$this->options_api->set( 'settings', $this->options->get_options() );
	}

To Reproduce

1. Fresh install wp rocket
2. Check the settings page
3. licence-data.php is removed but the license details' fields are empty.

Expected behavior
License should be validated properly.
