Check/Uncheck action for a product line in the category grid should be done only in the checkbox

[addison74]

I received a notification from a content editor that there were situations when he tried to edit the positions of the products in a category, but with a mouse click he deselected a few products. By saving the category these products were no longer listed.

I tried to reproduce this situation and I can say that in the end, out of fatigue or inattention, I managed to deselect products when editing their positions. I didn't even notice because it was on the other side of the table, only a smaller number of products in the category caught my attention.

My proposal is to disable the Check/Uncheck action of a product line as it is now and to be done only in the checkbox.

This seems to be implemented here #1379.
