fix: correctly assign name to both begin and end events for measures (#53588)

Summary:
Pull Request resolved: #53588

# Changelog: [Internal]

Since the `name` was already moved for the begin event, there is nothing to be moved for `end` event. Instead, we will be creating a copy for the `begin` event.

This was actually affecting some entries on a timeline, like component triggers (yellow ones).
