Does it make sense to set the profile even if browser is non-NULL?

I'm not really sure and tried to make the fix affecting as little as possible. 
Current code is using the browser's profile if there is a browser instance.

Fair enough.

+      params.profile = contents->profile();
     params.disposition = NEW_POPUP;
     params.window_bounds = initial_pos;
     params.window_action = browser::NavigateParams::SHOW_WINDOW;
