Importing products with same name in different nodes(categories) doesn't work

Description

Steps to reproduce:

1. Have a catalog with two entries in two categories but the same UriSegment (or the same name and an empty UriSegment).
2. Add this setting to appSettings.

<add key="episerver:commerce.UseLessStrictEntryUriSegmentValidation" value="true"/>

3. Import the catalog described in step 1.

Expected:
The two entries keep their UriSegment.

Actual:
One entry has an autogenerated UriSegment with random characters.
