Bug in current_cases fixture: missing case function or case function not the original one

[smarie]

Found while working on #211 👍

class MyClassName2:
    def case_bar(self):
        return "barval"

    @parametrize(dummy=['a'])
    def case_foo(self, dummy):
        return "fooval"


@parametrize_with_cases('val', cases=MyClassName2)
def test_function2(val, current_cases):
    ref = {
        "barval": MyClassName2.case_bar,
        "fooval": MyClassName2.case_foo
    }

    case_id, case_func = current_cases['val']
    assert case_id == val[:3]
    assert case_func is ref[val]

Raises a KeyError for the first case (bar)

Another issue:

from pytest_cases import parametrize, parametrize_with_cases


class MyClassName:
    def case_foo(self):
        return "fooval"


@parametrize_with_cases('val', cases=MyClassName)
def test_function(val, current_cases):
    assert val == "fooval"

    case_id, case_func = current_cases['val']
    assert case_id == "foo"
    assert case_func is MyClassName.case_foo

raises an AssertionError because case_func is a partial and not the original class function.
