Evaluate parent list class on merged changes

The binding for the class attribute of the parent list in change
metadata depends on the parent-is-current boolean. The boolean in-turn
depends on the rebase revision action. Formerly, if the rebase action
was not present at all (as it is not on merged changes) the boolean
would be left as `undefined` and the binding would not evaluate.

As a result, the class would not be set and the parent list would not
show numbers next to parents on merged merge changes.

With this change, the boolean is given a value whether or not the rebase
action is present and tests are updated to confirm this.
