c3t3.number_of_vertices() was not documented, and that is why the 
compatibility was not kept. It is the same as:

  c3t3.triangulation().number_of_vertices();

that is documented, in both 3.7 and 3.8. Use that as a replacement and should 
no longer ave problems.

number_of_vertices_in_complex() is not documented either, and is not what you 
expect. It should be named number_of_corners(), documented here:
