fix(updater): fix check for latest commit in local repository

Browse Source 
The previous check simply compared whether the last commit of the branch
was the same in the local and the remote repository.

This commit also checks whether the remote commit is an ancestor of the
local commit. This fixes the case where the local repository has new
commits after the last published commit.
