Reproducing steps:

1. Import https://github.com/ARMmbed/training-provisioning-release application.
2. The mbed-os.lib version should be https://github.com/ARMmbed/mbed-os/#f4790ce69f273f5138ff23bf628bbe0e3a62b9d2.
3. Perform publish (without any additional steps).
   Messages during the publish:

The result of current publish operation is changing of mbed-os version to d7eddf0f43c7746b15bc0832ad3e4df6f4ab445a,when the publish itself was empty (without any changes).
Expected behavior: mbed-os version should not be changes.
This behavior wasn't detected with previous cli versions.

@TaniaMirzin Can you try mbed CLI from this PR #290 ?
First uninstall any existing mbed CLI via pip uninstall mbed-cli
Then clone my fork - https://github.com/screamerbg/neo
And finally inside the cloned folder run python setup.py install, which might require sudo on Linux/Mac

When i installed mbed-cli from your fork i updated to version 0.8.3.
As i can see PR #290 is already merged to the main tree and its version 0.8.8, so i worked with it and not with 0.8.3.
I tried to perform the same steps and the bug is still reproducing.
I see also problem of recognizing added files during publish operation.
The problem can be reproduced after steps 1-3.
