[TYPO3-commerce] fix discount amount per user - not discount-groups

Well - a change in the uid should not be a problem - should it? The 
resulting price-object will also make use of those two hooks. And gladly 
the only reason why the price could be changed would be a scaled price. 
But there the discount should also be applied. I'll try and see what 
happens. Thanks so far.

Sure - maybe I pack it as small extension and provide it as 
commerce-addon in TER as it could be of general use. Then I could 
implement such 'fixed' discounts also by fe_group with an override by 
fe_user. And apply discount-flags to products and articles, so that 
selected articles can be enabled or disabled for discounts. Might maybe 
come handy. But first the job has to be finished and I have to find some 
sparetime again (quite busy currently).
