Copy column contents in getRawSamplesTableBuilderFromExisting for consistency

[mstange]

Main | Deploy preview

The other getRawXYZBuilderWithExistingContents functions do the same; the samples version is only called in places where we then overwrite the original table so it didn't really make a difference, but let's be consistent with the other tables and actually make it so that if you push to the builder columns, the original table is unaffected.
