fix: make AccessEntry equality consistent with from_api_repr (#2218)

* fix: make AccessEntry equality consistent for view entity type

* fix: make AccessEntry equality consistent for view entity type

* fix: use json.dumps() for normalizaiton of entity_id

* remove trailing whitespace and add test assertions

* revert back to the original code

* fix linting in `dataset.py`

* fix linting in `test_dataset.py`
