fix navigation path order (#1668)
fix navigation path order (#1668)

Solves a problem that the navigation path has a wrong order.
Sample navigation:
/MainPage
SettingPage?item=1
SettingPage?item=2

Currently it becomes /SettingPage?item=2/MainPage/SettingPage?item=1
and not /MainPage/SettingPage?item=1/SettingPage?item=2
