Check for version in list of installed versions

[jmacfar]

What does this PR do?

2016.3 breaks previous behavior of pkg.(install|remove) in that if multiple versions of one piece of software are installed, none are seen as installed and are not removable. Tested with w2k8/w2k12 client.

Previous Behavior

w8-cl1.salt.local:
    ----------
    Java Auto Updater:
        2.8.91.15
    jre8:
        8.0.730.2,8.0.910.15
    salt-minion:
        2016.3.1

$ salt 'w8-cl1*' pkg.remove jre8 version=8.0.730.2
w8-cl1.salt.local:
    ----------
    jre8:
        ----------
        current:
            8.0.730.2 not installed

$ salt 'w8-cl1*' pkg.remove jre8
w8-cl1.salt.local:
    ----------
    jre8:
        ----------
        current:
            8.0.910.15 not installed

New Behavior

$ salt 'w8-*' pkg.remove jre8
w8-cl1.salt.local:

@jmacfar Just a small lint error - can you clean that up really quickly? Then we can get this in.
