[MLGO] Remove extranous check lines from test input

This patch removes check lines from a test input. It was originally
copied from a test that had assertions automatically generated, but
given we only use it as an input, the check lines do absolutely nothing.
Remove them to improve readability of the test/prevent confusion.
