Bug 1353042

Description of problem:

The pages uses to assign an alert_profile to a resource are throwing exceptions.
So the page returns a 500, but since it is ajax, it just eats it.

Part of this looks like it was introduced in 91be50d but I'm unsure when this actually broke.

error reproduction:

    Go to alert profiles
    add an alert
    attempt to assign to a resource (add tags)
    nothing happens. rails console displays a bug



Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.Go to alert profiles
2. add an alert Profile
3. Go to newly added Alert Profile summary
4. Press "Edit assignments for this Alert Profile" button from Configuration button group.
That throws an error in log:
