This should fix some race conditions which made post-upgrade steps not
executed sometimes.

* each steps use an defaultActivateParameterDict so that activity they
  may create inherits the same tag, so that next step also runs after
  this). This makes it possible for example to use post-upgrade step on
  documents newly installed in upgrade step.
* use tag / after tag between upgrader steps instead of checking if
  previous alarm had errors. We also now allow force running only one
  step regardless of the previous step completion state, there was no
  strong reason to prevernt this.
* do not use two different active sense and fix method for alarms, just
  use an active sense method understanding `fixit` parameter
