After this, scaling unit triangular matrices with parents that don't have the diagonal initialized works.

julia> M = Matrix{BigFloat}(undef,2,2);
  
julia> M[1,2] = 3;

julia> U = UnitUpperTriangular(M)
2×2 UnitUpperTriangular{BigFloat, Matrix{BigFloat}}:
 1.0  3.0
  ⋅   1.0

julia> U * 2
2×2 UpperTriangular{BigFloat, Matrix{BigFloat}}:
 2.0  6.0
  ⋅   2.0

Probably needs #1350 for tests to pass.
