SUP-1709 Cannot use CiviCRM Import to remove data from a Contact field.

When perform import contact (update) with the empty column in csv file, expect that it should remove data from a Contact field. Looks like the importer skips columns which have an empty value. So, if you want to remove incorrectly set Email fields (eg. home location) being able to import a blank value into that field would be a great way to quickly fixing your data. Seems it’s not possible to do that.
