Force currentSpecification for ISO specs (#2040)

The `series.currentSpecification` property is set before the code that
processes ISO specs is run, and thus relies on the *computed* shortname,
which isn't the final one for ISO specs.

Code that processes ISO specs now overrides that property with the actual
spec shortname (note: we don't have a notion of levels for ISO specs today)
