#8446: avoid 0^0 in Selmer groups of number fields

-----------------------------+----------------------------------------------
In the case of a trivial number field, such as
{{{
K.<a> = NumberField(polygen(QQ))
}}}
the Selmer group function doesn't work, since the generator `a` of the
number field is 0, and when we're constructing polynomials we use the form
`coeff*a**i`. However, if `i==0`, we get an `ArithmeticError` since Sage
does not have conventions for `0^0`.
