sage/symbolic/random_tests.py wrongly depends on order of dict.values()

[sagetrac-cwitty]

The variable sage.symbolic.random_tests.full_functions is ordered in the same order as the .values() method on a dict, which is not necessarily reproducible. (I'm a little curious as to why the order in fact does seem to be reproducible, across multiple platforms, etc., but changes with the addition of seemingly unrelated code -- but not curious enough to investigate.)

Anyway, the current code is clearly wrong. I'll have a fix in a few minutes.

This should fix the strange random_tests.py doctest issue from #8988, and possibly reduce the churn in the random_tests doctest results.

This patch fixes the problem, and also seems to fix the random_tests.py problem with #8988 (as expected).

Works for me and removes the necessity of interfering in #8988.
