Remove tests_isolated from default tests run with pytest (#1362)

* Remove tests_isolated from default tests run with pytest

This is to prevent pytest from running tests together which need to be isolated.

In the future we should try to fix these tests so they don't need to be run isolated from others.

* Updated CHANGELOG in preparation for a new release

While this bug won't impact cmd2 development itself, it will create chaos for consumers such as Linux distros trying to execute cmd2 tests when packaging it.
