Bug fixes

• ❗️ Fix segments evaluation logic given 0% rollout segments. #180 #181.

Note, previously, the evaluation of segments falls through to the next segment for non-rolled out users (e.g. 0% rollout percentage of a segment). The intended behavior is that If the entity context matches the constraints in a segment, it should stop evaluating the following segments. Specifically, for 0% rollout segment, it shouldn't go to the next segments.
