Changed dummy ic_no to the same value who is an admin

For testing purposes, make the customer with ic_no G0587235M an admin.
Finished user booking list on My Bookings header tab

User is still a dummy admin user.
Reversed last commit 0455bba made by Steven Kester Yuwono

getBookings() only returns user booking information.
booking_list.php will later call getRestaurantDetails(), because it needs a lot of the restaurant's information.
