result from state.highstate adds retcode=x also to other successful states for same minion

Description of Issue

When executing a state.highstate one of the many states may fail.
But in that case many other states also get the additional result-property retcode=2.
Still, "result=true" is set for all of them.

Setup

No special setup, just a master and several minions.
The sls files have several standard rules (test.show_notification, file.absent, file.managed, cmd.run, pkg.latest, pkg.purged, schedule.present and schedule.absent)

Steps to Reproduce Issue

Define an SLS for which one state will fail.
Run state.highstate.
See the failing state in the output, it has result=false and retcode=2.
See that several other states have result=true, but also retcode=2.
For minions where no states fail, the other states do not get retcode=2 added.

Start by reproducing the issue with state.highstate using an SLS containing standard rules such as test.show_notification, file.absent, file.managed, cmd.run, pkg.latest, pkg.purged, schedule.present, and schedule.absent. Compare the returned properties for the failing and successful states; done means only the failing state reports retcode=2, while successful states retain result=true without that retcode.
