M1.5: Fix queryValidator and queryTestCases

[mcamardon]

After creating the genericTestCases, all the test cases that were common between header, query and json, were put together in a new file (genericTestCases.js). As a consequence, for the queryTestCases.js file, it is necessary to only leave the test cases regarding only query and remove the rest that were already moved. This is also an opportunity to finish changing the queryVlidator function to use the functions in format functions as there will need to be done some changes in the queryTestCases.

AC:

1. Clean queryTestCases
2. Implement functions in formatFunctions.js in queryValidator function.
