fix ui-external url

[qdirks]

When browser-sync is serving files, this is what it prints in the console:

[Browsersync] Access URLs:
 --------------------------------------
       Local: http://localhost:3000
    External: http://192.168.0.242:3000
 --------------------------------------
          UI: http://localhost:3001
 UI External: http://localhost:3001         <-- This is not the external access url
 --------------------------------------
[Browsersync] Serving files from: ./

This pull request changes it to this:

[Browsersync] Access URLs:
 --------------------------------------
       Local: http://localhost:3000
    External: http://192.168.0.242:3000
 --------------------------------------
          UI: http://localhost:3001
 UI External: http://192.168.0.242:3001
 --------------------------------------
[Browsersync] Serving files from: ./
