[Merge] ~slyon/network-manager:netplan-integration into network-manager:ubuntu/master

[Sebastien Bacher]

Review: Needs Fixing

Confirming the issue raised by Danilo, the script failed to migrate several connections using a ca-cert and pointing to a filename stored in directory with a 'é' in its name

it also displayed some warnings (translated from french so the wording might not be the correct english one)

> Warning: there is another connection with the name '...'. Refer to the connection using its uuid '...'
