Allow import to skip errors

[superdav42]

Description

This appears to be a bug that has been in the codebase 3+ years? Maybe it never worked. The "skip error entries" essentially does nothing when importing products or customers. With this PR they can be skipped as expected.

Fixed Issues (if relevant)

1. Magento 2.2.2-dev - CSV Import, skip errors not working magento-engcom/import-export-improvements#75: Magento 2.2.2-dev - CSV Import, skip errors not working
2. Magento 2.2.2-dev - CSV Import, skip errors not working #12808: Magento 2.2.2-dev - CSV Import, skip errors not working

Manual testing scenarios

1. Import csv with one or more validation errors
2. Interface will indicate an error was found but allow user to continue
