Short description of error

Exporting a Blender object with modifiers to X3D fails. The exporting script tries to modify a temporary mesh object name, which is not allowed.

Exact steps for others to reproduce the error

Reproduction:

Take any mesh (default cube in the default scene is enough),
Add a modifier like "Subdivision Surface",
Export to X3D with "Apply Modifiers" selected (by default it is).

Export fails with the following error:

Info: starting X3D export to '/home/michalis/Desktop/a.x3d'...
Traceback (most recent call last):
  File "/home/michalis/installed/blender/2.82/scripts/addons/io_scene_x3d/__init__.py", line 241, in execute

    me.name = obj.name.rstrip("1234567890").rstrip(".")
AttributeError: bpy_struct: attribute "name" from "Mesh" is read-only

location: <unknown location>:-1

I'll submit a patch for this shortly.

Thx for the fix!

This has actually been reported before, see {#68452], will merge these reports... (and in this case, will merge the older one into the newer one, because we have the fix provided here...)
