Bug#987170: python3-dolfinx: python module missing wrapper functions

[Matsievskiy S.V.]

Package: python3-dolfinx
Version: 2019.2.0~git20210130.c14cb0a-4
Severity: important

Dear Maintainer,

Python3 module misses some C++ wrapped functions. One of those functions is
`dolfinx.cpp.la.scatter_forward`

In order to reproduce the problem run the following Python3 code:
```python
import dolfinx
from mpi4py import MPI
mesh = dolfinx.UnitSquareMesh(MPI.COMM_WORLD, 8, 8,
dolfinx.cpp.mesh.CellType.quadrilateral)
V = dolfinx.FunctionSpace(mesh, ("CG", 2))
uex = dolfinx.Function(V)
uex.interpolate(lambda x: 1 + x[0]**2 + 2 * x[1]**2)
dolfinx.cpp.la.scatter_forward(uex.x)
```

This code throws error `AttributeError: module 'dolfinx.cpp.la' has no
attribute 'scatter_forward'` on Debian but runs just fine on the dockerized
jupyter notebook provided by https://github.com/jorgensd/dolfinx-tutorial
