Issue Summary

The Clone Schedule feature only clones the first Rotation of the original schedule when there are multiple rotations existing.

Steps to Reproduce

1. Create an On-call Schedule with more than 1 Rotations.
2. Hover on the schedule to clone it to a new schedule.

Expected Results

All Rotations within the original On-call Schedule should be all cloned to the new On-call Schedule.

Actual Results

Only the first Rotation is successfully cloned to the new On-call Schedule.

Workaround

After cloning the On-call Schedule, please manually re-create the rest of Rotations from the source to the destination On-call Schedule.
