ambiguous evaluate

julia> k,a = cyclotomic_field(3)
(Cyclotomic field of order 3, z_3)

julia> P,(x,y) = PolynomialRing(k,[:x,:y])
(Multivariate Polynomial Ring in x, y over k, AbstractAlgebra.Generic.MPoly{nf_elem}[x, y])

julia> evaluate(x//y,[a,a])
ERROR: MethodError: evaluate(::AbstractAlgebra.Generic.Frac{AbstractAlgebra.Generic.MPoly{nf_elem}}, ::Vector{nf_elem}) is ambiguous. Candidates:
  evaluate(f::FracElem{T}, V::Vector{U}) where {T<:RingElement, U<:RingElement} in AbstractAlgebra at /home/simon/.julia/packages/AbstractAlgebra/ZmWFo/src/Fraction.jl:606
  evaluate(f::FracElem{<:MPolyElem}, v::Vector; ErrorTolerant) in Oscar.ModStdQt at /home/simon/.julia/dev/Oscar/experimental/ModStd/ModStdQt.jl:11
Possible fix, define
  evaluate(::FracElem{T}, ::Vector{U}) where {T<:MPolyElem, U<:RingElement}
