[CrOS Settings] Fix blink ripple of back arrow in internet_detail_page.

Fix unnecessary blink of ripple effect seen at back arrow in Wi-Fi
details screen. This was caused because both settings_subpage and
internet_detail_page were focusing their own UI elements, causing
a flickering. This is solved by setting the settingId param in the url
so then settings_subpage does not attempt to focus its back button.
