Improve `refine` output when edge entities are not computed

```Python
import dolfinx
from mpi4py import MPI

mesh = dolfinx.mesh.create_unit_square(MPI.COMM_WORLD, 10, 10)
# mesh.topology.create_entities(1) # This is missing
dolfinx.mesh.refine(mesh)

# Output:
# > IndexError: vector
```

This should result in an output of dim 1 entities not having been computed.
