Prevent unsaved changes dialog from appearing after item is deleted

[azrikahar]

fixes #8146

Reported Bug

When there's unsaved edits and the item is deleted, the unsaved changes dialog still shows up despite the item already cease to exist:

Solution

Clear the edits state after item is deleted. Basically referred the edits.value = {} usage from discardAndLeave():

directus/app/src/modules/collections/routes/item.vue

Lines 504 to 509 in 3636215

	function discardAndLeave() {
	if (!leaveTo.value) return;
	edits.value = {};
	confirmLeave.value = false;
	router.push(leaveTo.value);
	}
