2.2 Importing Group Products No Longer Works

[mzenner1]

As of 2.2, group products no longer import properly. Using the sample data given on the system->import page, it will import the group product (the product type is correct), but no longer associate the simple products to the grouped product. This was confirmed working in 2.1.7, but looks to be broken in 2.2.1 and 2.2.2.

@mzenner1, thank you for your report.
We've created internal ticket(s) MAGETWO-85900 to track progress on the issue.

Hi @mzenner1 , I've created PR to fix this issue. Currently only for 2.3-develop branch. If accepted I'll create backport to 2.2-develop branch.

Issue has been created because of new functionality in 2.2 & 2.3 for duplicate SKU's. Every SKU is lowercased. In this function it was forgotten to change SKU to lowercase.

@dmanners Could you add import/export label to this issue. Thanks!

@mzenner1 - Have you ever got a chance to solve this issue. If you found any solution, please let me know. Thanks

@sasilinux I fixed in that PR. Just need to fix unit test but is easy. Will fix it.

@PieterCappelle @dmanners FYI I added the Import/Export label.
