Should not be able to launch queued instance snapshot.

[Jake Dahn]

Currently, after I take an instance snapshot, I am given the option to launch it immediately: http://stsh.me/1QQ

Expected: I should not be able to launch an instance snapshot (image) until it is out of the queued state, and ready to actually launch.

Actual: I am immediately able to click launch, which will result in an error.

    LaunchAction button enabled only if image
    is in 'active' state

    Fixes bug 959705. Affects snapshot images,
    that can currently be launched when still in
    queued status.
