2.8.13.rc1: sage/rings/arith.py doctest failure

[mabshoff]

We get:

File "arith.py", line 2393:
     sage: continued_fraction_list(sqrt(4/19))
Expected:
     [0, 2, 5, 1, 1, 2, 1, 16, 1, 2, 1, 1, 5, 4, 5, 1, 1, 2, 1, 18]
Got:
     [0, 2, 5, 1, 1, 2, 1, 16, 1, 2, 1, 1, 5, 4, 5, 1, 1, 2, 1, 15, 2]

This is fallout from #1196:

With 2.8.12 we get:

sage: n(sqrt(4/19))
0.458831467741123

With 2.8.13.rc1 we get:

sage: n(sqrt(4/19))
0.458831467741124

Regarding #1228 change the doctest to the new answer.
It's actually much better.

Merged in 2.8.13.rc2.

Fixed the doctest directly :)
