Test: improve bitwise tests (#73)

* improve bitwise tests

* fix test

* assert xor,or and uptade ptr

* delete bitwise_test.cairo

* rename file

* Add let to declaration

* Rename test

* Re order values in the correct way

* Fix expect order

* Format and clean file

* Format code

* Remove non-used imports

* Add missing import and run tests
