Feature services do not use specified features correctly

[achals]

Expected Behavior

Given a minimal example:

file_source = prep_file_source(df=simple_dataset_1, timestamp_field="ts_1") as file_source:
entity1 = Entity(name="test1", join_keys=["id_join_key"])
feature_view_1 = FeatureView(
    name="test1", entities=[entity1], source=file_source,
)
feature_service = FeatureService(name="fs_1", features=[feature_view_1[["string_col"]]])

The feature service should only contain a single feature, string_col.

Current Behavior

The feature service should contains all the features for the feature view.

Steps to reproduce

test_update_feature_services_with_inferred_features exhibits this behaviour
