DolphinViewContainer: make sure searchbox is initialized before setSearchPath
If searchBox is not initialized, it can't be updated properly with setSearchPath due to some buttons not existing. There is also just no need to update it if it's not initialized.
Make sure we check for it's initialized during setting the search path.
