Problem Description

Empty strings are not actually ignored like they are supposed to.

Steps to Reproduce

1. Create a CSV file with the following contents:

_id,a
6017fd8caeb4b44312f7254f,1
6017fd8eaeb4b44312f72550,

2. Import that file using CSV, with “Ignore empty strings checked”

Expected Results

The second document should not have an `a` key.

Actual Results

The second document has an `a` key with an empty string as its value.
