Attempt to run dnf update before the migration (#58)

Browse Source 
* Attempt to run dnf update before the migration.

While a migration will generally work without first running dnf update, thera
are several advantages of attempting to run an update first:

* We catch corner cases that an update will solve.

* Since we're running a distro-sync at the end, it effectively updates anyways
  and the same things that will break a distro-sync will often times break an
  update.  By attempting to run the update first we will discover those
  breakages before we put the system into an unstable state and we can bail out
  if the update fails, preventing a potentially disastrous outcome.
