[ros-release] Triggering pre-release jobs for a yet-to-be-released package fails

[Isaac Isao Saito]

ROS-Releasers,

I'm gettting an error on the browser when I try to trigger a
pre-release job for a package that's yet to be released (listed on
rosdistro without version). Any idea what's wrong?


```
    Failed......

    We failed to triger your pre-release jobs... Check out the output below.

I seem to be able to create jobs for released packages.

Thanks!
