[TYPO3-commerce] Strange empty link in navigation while browsing third level

[Rik Willems]

Hi Erik,

There is a known bug in the navigation class (it should be in Forge). 
This creates the empty li. The class is quite complicated and in my 
opinion needs some other work too. I have been looking into it but 
haven't created a solution yet.

Greets, Rik
