Is there a downside to making a copy of `urls_to_open` here and passing it as a
modifiable argument to install_chrome_app::InstallChromeApp(..) ? (i.e. do all
the processing here, and move the logic being added to
StartupBrowserCreator::ProcessCmdLineImpl() to
install_chrome_app::InstallChromeApp() instead? Then move the call to
ProcessLaunchURLs down after InstallChromeApp.

If there are multiple last_opened_profiles, this will happen for each one.

 
-    if (command_line_.HasSwitch(switches::kInstallChromeApp)) {
-      install_chrome_app::InstallChromeApp(
-          command_line_.GetSwitchValueASCII(switches::kInstallChromeApp));
-    }
-
     // If this is an app launch, but we didn't open an app window, it may
     // be an app tab.
     OpenApplicationTab(profile);
