crash for missing hardware "hardware::storage:cd"

Affects Status Importance Assigned to Milestone
software-center (Ubuntu)

Bug Description

- trivial typo fix with almost zero regression potential
- a regression test is enough

If there is a missing hardware: "hardware::storage:cd" for a app it will crash with. This was uncovered when running the testsuite with "debtags" fully installed and updated.

    descr = descr % postfix
TypeError: unsupported operand type(s) for %: 'NoneType' and 'str'

This is due to a typo in softwarecente/
