IIUC, what's happening here is that they bundle the extension with Thunderbird 38 so it's installed and enabled by default; so when you create a new Thunderbird profile, /usr/lib*/thunderbird/distribution/extensions/{e2fda1a4-762b-4020-b5ad-a41df1933103}/ will get copied to ~/.thunderbird/<PROFILE_NAME>/extensions; that also happens if you run 38.0.1 for the first time and didn't have the Lightning extension already installed (I was surprised to see the calendar pane in Thunderbird after updating to 38.0.1, since I didn't have that extension installed previously). Also (IIUC) Lightning will be updated in your profile, just like any other user-installed extension. So what you can do is just copy the dir from /usr/lib*/thunderbird/distribution/extensions and restart Thunderbird or re-install it from addons.mozilla.org, I think either would lead to the same result

You should file a bug so that the issue is tracked/fixed.
