When we add the preference "Searching for Wi-Fi networks...", we didn't provide a key to the preference. As a result, each time when we get access point update and try to show such tile, it creates a new one, and results in multiple entries of such tile. Adding a key to the preference will prevent the multiple entry from being added. Test: Manual - 1. Turn wifi off and on several times, verify that there is only one entry of "Searching for Wi-Fi networks..." when initializing the wifi access point list. 2. Verifies that when the access point list is established, the "Searching for Wi-Fi networks..." entry is gone.
