Related to #654

During replay, if an activity doesn't not exist in the history, the replay would run into this branch and throw some weird error messages.

It will throw error like:

java.lang.IllegalArgumentException: No value found for mutableSideEffectId=17eb87a3-bbd5-3310-b2c5-48ac24000057, during replay it usually indicates a different workflow runId than the original one
