#13300: slice and __getitem__ do not work over unramified extensions of padics

---------------------------+------------------------------------------------
There are some strange results when indexing into an element of an
unramified extension.
In the following example, I think it would make more sense to return an
element in the residue field:
{{{
sage: K=Qp(3,5)
sage: R.<a> = K[]
sage: L.<a> = K.extension(a^2+a-1)
sage: a[0]
[0, 1]
}}}
Slices do not work at all currently:
{{{
sage: a[0:2]
TypeError
}}}
