Fix test

Lines 49 to 52 in 070e1eb

	def test_old_version(deprecated: str, plural: bool, expected: str) -> None:
	expected = r""
	with pytest.raises(RuntimeError, match=expected):
	_deprecate.deprecate(deprecated, 1, plural=plural)

Somehow, this test managed to immediately discard the expected argument and set it to an empty string instead.

The code originated in #6184
