Remove all unnecessary tests files

Right now almost all ts code files have an associated file for unit tests. However, only few of those files have real unit tests, most of them only have one default test (for checking if the object can be created). All those unused test files should be deleted, because are not really needed and require maintenance from time to time (mainly when adding new ts files and when modifying the constructors).
