Update PriorityQueue.js

[PradeepG-07]

Changed the default priority of a item to value of the item if the priority is not provided manually in the add() method.
Now it resolves the issue #1070
describe('priorityQueue Test:', () => {
it('should return correct priorityQueue results:', () => {
const pq = new PriorityQueue();
pq.add(1);
pq.add(2);
pq.add(3);
pq.add(4);
expect(pq.toString()).toBe('1,2,3,4');
expect(pq.poll()).toBe(1);
expect(pq.poll()).toBe(2);
expect(pq.poll()).toBe(3);
expect(pq.poll()).toBe(4);
});
});
It polls out values as 1,2,3,4

@PradeepG-07 I am not sure I can though. I need to be a maintainer to do that
