// Add a tab with its session history restored from the SessionRestore and

// |tab_index| gives the index to insert the tab at. |selected_navigation| is
// the index of the SerializedNavigationEntry in |navigations| to select. If
// |extension_app_id| is non-empty the tab is an app tab and |extension_app_id|
// is the id of the extension. If |pin| is true and |tab_index|/ is the last
// pinned tab, then the newly created tab is pinned. If |from_last_session| is
// true, |navigations| are from the previous session. |user_agent_override|
// contains the string being used as the user agent for all of the tab's
// navigations when the regular user agent is overridden. If
// |from_session_restore| is true, the restored tab is created by session
// restore. |last_active_time| is the value to use to indicate the last time the
// WebContents was made active, if this is left default initialized then the
// creation time will be used. Returns the WebContents of the restored tab.
