Description of problem:
While attempting to use `reapply` in the Nmstate project, we have found that in case the wired setting is not defined/added to the new profile, the reapply operation will fail, claiming that the mac address change is not supported.

`nm-device-error-quark: Can't reapply changes to '802-3-ethernet.cloned-mac-address' setting (3)`

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Fetch existing profile using `get_connection_by_id`.
2. Create new profile using SimpleConnection.new()
3. Add to the new profile the wanted setting (connection and IPvX in our case) using `add_setting`. (do not include the wired setting)
4. Replace existing profile settings with the new profile setting using `replace_settings_from_connection(new_profile)`.
5. Commit the existing profile changes using `commit_changes_async`.
7. Execute reapply with the existing profile.

Actual results:
Step 7 fails with the following error:
`nm-device-error-quark: Can't reapply changes to '802-3-ethernet.cloned-mac-address' setting (3)`

Expected results:
Reapply should succeed because no wired changes have been requested.

Additional info:
Workaround: 
Fetching the wired setting from the current profile and using it in the new profile has resolved the problem.
