Fix bug where the problemresolve can put a pkg into a heisenstate
The problemresolver will set the candidate version for pkg P back to the current version if it encounters an impossible to satisfy critical dependency on P. However it did not set the State of the package back as well which lead to a situation where P is neither in Keep,Install,Upgrade,Delete state. Note that this can not be tested via the traditional sh based framework. I added a python-apt based test for this. LP: #1550741 [jak@debian.org: Make the test not fail if apt_pkg cannot be imported]
