Caused by rBcfa53e0fbeed: Refactor: Move normals out of MVert, lazy calculation

Short description of error
Run below code with mesh has shapekey will cause crash as EXCEPTION_ACCESS_VIOLATION.
bpy.data.meshes['Cube'].shape_keys.key_blocks['Key 1'].normals_vertex_get()

Exact steps for others to reproduce the error

  1. open attached .blend
  2. press run script of text editor, or run bpy.data.meshes['Cube'].shape_keys.key_blocks['Key 1'].normals_vertex_get() in python console

or

  1. launch blender
  2. add cube
  3. add one or more shapekey to cube
  4. run bpy.data.meshes['Cube'].shape_keys.key_blocks[any_key(0,1,... or "Basis", "Key 1" and so on )].normals_vertex_get() in python console
