At the moment the Git history of a user branch is not very useful since
it always reads as "Create account", "Update account", "Update account",
"Update account" etc. Make the commit messages more specific to the
actual update. For this callers of AccountsUpdate are now required to
provide a commit message for account creations and account updates.
Having specific commit message also makes debugging easier. E.g. if
there is bad account update it is easier to identify the code that was
doing it.
