A first batch of Sonar fixes

[davidusb-geek]

This is just a first fix batch of the issues found by Sonar.

@GeoDerp I have started this but I can see that now the 44 issues labeled as high priority are on these two files:

• src/emhass/static/configuration_script.js
• src/emhass/static/script.js

I may lack the js skills to solve those ;-)
