(trunk web) fix warnings in tr_urlIsValidTracker() and tr_urlIsValid() found by llvm's scan-build. 

scan-build found similar warnings in these two functions relating to allowing NULL pointers to be passed as arguments to functions that don't allow NULL. So now those NULL checks are made explicit before the function calls.
