[BUG] setindex!(::BlockSparseArray, ::Array, ::BlockIndexRange) errors

[ogauthe]

Issue: setindex!(::BlockSparseArray, ::BlockIndexRange) fails for any AbstractGradedUnitRange

g0 = blockedrange([2])
bsa0 = BlockSparseArray{Float64}(g0, g0)
bsa0[Block(1,1)[1:2,1:2]] = ones((2,2))  # Ok

g = gradedrange([TrivialSector()=>2])
bsa = BlockSparseArray{Float64}(g, g)
bsa[Block(1,1)] = ones((2,2))  # Ok
@show bsa[Block(1,1)[1:2,1:2]]  # Ok
bsa[Block(1,1)[1:2,1:2]] = zeros((2,2))  # MethodError

ERROR: MethodError: no method matching LabelledNumbers.LabelledInteger{Int64, TrivialSector}(::Int64)
The type `LabelledNumbers.LabelledInteger{Int64, TrivialSector}` exists, but no method is defined for this combination of argument types when trying to construct it.

Closest candidates are:
  (::Type{LabelledNumbers.LabelledInteger{Value, Label}} where {Value<:Integer, Label})(::Any, ::Any)
   @ LabelledNumbers ~/.julia/packages/LabelledNumbers/Pn1xf/src/labelledinteger.jl:2
  (::Type{T})(::T) where T<:Number
   @ Core boot.jl:900
  (::Type{T})(::BigFloat) where T<:Integer
   @ Base mpfr.jl:403

Some type information was truncated. Use `show(err)` to see complete types.

The error is detected in BlockSparseArrays, however it looks pretty similar to previous issues with dual axes: the problem may be in GradedUnitRanges.
