QML module is not version stable

[dobey]

This component is not properly versioned in a stable way that aligns with the UITK versioning. As a result, apps are broken simply by newer versions of the package being included in updates.

For example, if one has an application that uses Ubuntu.OnlineAccounts 0.1, but was still using the older Ubuntu.Components import, the newer version of Ubuntu.OnlineAccount imports the newer Ubuntu.Components, which creates conflicts, and results in various aspects of the app being broken, in particular many elements have improper theme rendering.

As a supported part of the SDK, this should never happen, and QML imports should be version stable.
