Short description of error
Dupplicated objects are created (but not visible) when reloading a linked library.

Exact steps for others to reproduce the error

Create a blender file with just a cube and save it
Create a new blender file, delete the default cube and link the other cube
** File -> Link -> (select file) -> Object -> Cube
Reload the library
Select "Blender File" from the "Scenes", "View Layer", etc dropdown Select the linked file and click "Reload"

This error message shows on the bottom:
Lib Reload: Replacing all references to old data-block 'OBCube' by reloaded one failed, old one (2 remaining users) had to be kept and was renamed to 'OBCube~000'

The blend file will show repeated objects as shown in the attached screenshot.

I can confirm the issue.

System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.92

Blender Version
Broken: version: 2.83.0, branch: master, commit date: 2020-06-03 14:38, hash: 211b6c29f7
Worked: version: 2.82 (sub 7), branch: master, commit date: 2020-03-12 05:06, hash: 375c7dc4ca

Saving & reloading the file purges those additional data-blocks (it happens also with collections).

Havent checked further, but looks like a bug to me, This kicks in:

Note that this should not happen - but better be safe than sorry in this area,
at least until we are 100% sure this cannot ever happen.
Also, we can safely assume names were unique so far,
so just replacing '.' by '~' should work,
but this does not totally rules out the possibility of name collision.
