test(sports): treat an adopted sports_helpers copy as parity, not missing (#777)

* test(sports): treat an adopted sports_helpers copy as parity, not missing

The scoreboards deleted their copies of the sports_helpers bodies and
constants when they adopted SportsHelpersMixin (ledmatrix-plugins
#563/#564), so the 19 parity tests in test/test_sports_helpers.py failed
whenever LEDMATRIX_PLUGINS pointed at a plugins checkout. A copy that is
gone now counts as adopted when the plugin imports
src.common.sports_helpers, as the stage 3/4 and game-over parity tests
already do; a copy that remains must still match.

* test(sports): _adopted checks for a real import via the AST, not a text match

 The parity class is what keeps "byte-identical" true after this lands. Point
