Problems raising a UTS to a negative integer power
The code below raises an unnecessary error. The problem
is in sttaylor.spad/powern, where no distinction between rational and integer powers are made.
The fix is easy. In fact, I just realize that the problem does not exist in SUPS, so we can just take the definition there.
