Problems we have are that while compiling some parameters are left blank at configconstants.ts and config.json files
if add new language item, or add href to siteurl property it's disappeared after compiling and running the app.
for example, after we run the command "npm run start" it terminal.
The file configconstants.ts was stayed by default with empty string siteurl = ''
In the file config.json new language wasn't added
