mvappend() doesn't accept multivalue column references

[ronja-ui]

Describe the bug

In general, mvappend() accepts column references. However, if the column is a multivalue column, mvappend() returns error.

Expected behavior

Multivalue column references should work as well.

How to reproduce

This one works:

| makeresults
| eval name="Alice"
| eval employees=mvappend("Bob", name)

This one doesn't:

| makeresults
| eval fruits=mvappend("banana", "apple", "pear")
| eval moreFruits=mvappend("mango",fruits)
