Multiple configurable_variations attributes not supported

[Morgy93]

If you provide multiple attributes for configurable_variations only the first one is imported.
For example: sku=1,color=red,size=1|sku=2,color=blue,size=2
Only color is added to the configurable product as configurable attribute variation.

@Morgy93 Thanks for reporting. I'll fix it with one of the next versions.

@Morgy93 I've released version 3.1.0-beta14 if you're on Magento 2.3.x. If you're on Magento 2.2.x please use 2.2.0-beta12. Keep me updated if everything works as expected. If not, feel free to re-open the issue.
