TST: Fix check() test utility function to detect all list differences

Browse Source 
The check() function in zipline.utils.test_utils was only comparing
lists up to the length of the shortest list. This fix uses
izip_longest instead of izip so it compares up to the length of the
longest list, which among other things means that it will now
correctly report when one list is empty and the other is not.
