Notifications service getFormNotificationByHandle method is broken

[jedso]

Describe the bug

I went to use getFormNotificationByHandle() for some custom module logic, i.e.
Formie::$plugin->getNotifications()->getFormNotificationByHandle($form, 'notificationHandle');

...but it was always returning null. This is due to the method always returning the 0 index of the whereMultiple array:

formie/src/services/Notifications.php

Lines 74 to 77 in 79876a8

	public function getFormNotificationByHandle(Form $form, string $handle): ?Notification
	{
	return ArrayHelper::whereMultiple($this->_notifications(), ['formId' => $form->id, 'handle' => $handle])[0] ?? null;
	}

In my case, the ArrayHelper::whereMultiple($this->_notifications(), ['formId' => $form->id, 'handle' => $handle]) call by itself was returning a valid notification but it had an index of 9, and hence would never be returned:

Steps to reproduce

1. Make sure you have >1 notifications created
2. Add a new notification to a form
3. Grab the form, store in $form, and call Formie::$plugin->getNotifications()->getFormNotificationByHandle($form, 'newNotificationHandle'); with your new notification handle, and observe how it will always return null.

Ah, a great point! Fixed for the next release. To get this early, run composer require verbb/formie:"dev-craft-5 as 3.0.15".
