backslash operator \ for tall Toeplitz matrices displays wrong error message

[mzaffalon]

ToeplitzMatrices v0.8.2 gives the following error message on tall matrices:

julia> A = Toeplitz(1:4, [1.0,0,0])
4×3 Toeplitz{Float64, Vector{Float64}, Vector{Float64}}:
 1.0  0.0  0.0
 2.0  1.0  0.0
 3.0  2.0  1.0
 4.0  3.0  2.0

julia> A\randn(4)
ERROR: DimensionMismatch: second dimension of A, 3, does not match length of x, 4

Maybe a not implemented error method or an implicit conversion to Float64 would be better.
