Cannot copy from multi-user custom field to single-user field (custom or system)

Description

Reported by JIRA Cloud users as https://jira.atlassian.com/browse/JRA-44848

Although it doesn't necessarily make much sense, it should be possible to copy from a multi-user picker field to a single-user field (such as Assignee) - in that case, only the first user should be used.

Likewise, it should be possible to copy from a single-user field to a multi-user field.
