Fix sonarqube code smells

Making changed regarding code smells. Some variables being declared twice while in scope.
renaming some modelFileName in ApexFiles.js that is being declared while there is a constant with the same name.
renamed some of the for loop control variables so that sonarqube doesnt see it as an issue
Made changes based on reviews
