`insupport` for reshaped univariate distributions returns 0-dim BitArray rather than Bool

[penelopeysm]

Another edge case with reshaped distributions:

julia> insupport(reshape(Normal(), 1), [0.5])
0-dimensional BitArray{0}:
1

This comes from here, as size(d.dist) == () and hence reshape(x, size(d.dist)) is a 0-dim array:

Distributions.jl/src/reshaped.jl

Lines 32 to 34 in b0ae395

	function insupport(d::ReshapedDistribution{N}, x::AbstractArray{<:Real,N}) where {N}
	return size(d) == size(x) && insupport(d.dist, reshape(x, size(d.dist)))
	end
