- added functionality to set values to 0 when deleting structure(not for mapping)

- added unit test

Made some changes after Christian`s review on pull request
- remove/edit comments
- BoolType and ContractType return VoidType after delete

- fixed constructor_arguments test

- fixed set to 0 when deleting variable from stack
- changed test case to test that
