Subject: [PATCH] (core) Avoid an error when pasting data with first row
 shorter than the rest

Summary:
Pasting data like `A\nB\tC` was failing because the first row, used for
checking column type (to handle rich data), was failing on an undefined value.

Discovered while trying out the fix in https://phab.getgrist.com/D3110.

Test Plan: Tested manually. The case mentioned now works as expected.
