Webui of SensESP app 'automatic server discovery' does not show correct after switching pages in the tab control

[GHBLoos]

3.0.0.b2

When you check or uncheck the 'automatic server discovery', it shows or hides the hostname and port textboxes. But when you switch to another page (like the 'status' tab) and come back, it is possible to see a checked 'automatic server discovery', but also the textboxes below. It fooled me a few times because you think you are on 'manual', but you are on 'automatic'.

I have not checked if the code is correct behind the webui, so maybe it shows that you are on 'automatic', but it is stored as 'manual'.
