#10846: Conversion of PowerSeries -> SR bug

-------------------------+--------------------------------------------------
If I convert a powerseries into the symbolic ring, it does not have any
variables.
{{{
sage: R.<x> = PowerSeriesRing(QQ)
sage: s = R([1,2,3,4,5],prec=10)
sage: s
1 + 2*x + 3*x^2 + 4*x^3 + 5*x^4 + O(x^10)
sage: SR(s)
1 + 2*x + 3*x^2 + 4*x^3 + 5*x^4 + O(x^10)
sage: SR(s).variables()
()
}}}
Running simplify() fixes it:
{{{
sage: SR(s).simplify().variables()
(x,)
}}}
