(core) Fix JS error when pasting data with merged cells.

Browse Source 
Summary:
Pasting data with merged cells from Excel (or from HTML tables with colspan/rowspan),
we used to get "Cannot read property 'displayValue' of undefined".

Fix it by assuming that some cell values may be empty.

Test Plan: Added test case reproduces the failure without the fix, and passes with.
