Fix build slice level breakdown

[ticheng-aws]

Description

In case where a slice with multiple leaves, it is possible that any one of the leaves has 0 invocations for a specific breakdown type. For instance, let's consider a slice with three leaves: leaf A with a score count of 5, leaf B with a score count of 0, and leaf C with a score count of 4. In this situation, we only compute the timing type slice start/end time based on leaf A and leaf C. This is because leaf B has a start time of zero. And it doesn't represent an actual timing; rather, it indicates no invocations.
