package level flycheck checks wrong packages

[Veykril]

@Veykril Sorry for the late response. I tried to modify the crates/stdx/src/lib.rs file and run flycheck afterward, and its behavior clearly differs from cargo check -p stdx. For some reason, flycheck runs check for base-db and not for stdx. Here are the logs and the recorded video for this case.
