System Information
Operating system: Linux
Graphics card: GTX 1070

Blender Version
Broken: 2.80
Worked: -

Short description of error
related to https://developer.blender.org/T70287
If used in the correct/wrong way, the dissolve vert function can create duplicate faces

Exact steps for others to reproduce the error
Based on the default startup:

add a Tetrahedron in your favorite way (for example a cone with 3 segments and filled base plate)
dissolve one edge of the tetrahedron with X->Dissolve Edges and F6->Dissolve Verts=0 so the vertices stay the same
dissolve one of the vertices that now only have 2 adjacent edges with X->Dissolve Vertices
you should be left with a duplicate triangle with normals pointing in different directions.
