The previous commit added low-level tests to ensure that the packed-refs iterator did not enumerate excluded sections of the refspace. However, there was no guarantee that these sections weren't being visited, only that they were being suppressed from the output. To harden these tests, add a trace2 counter which tracks the number of regions skipped by the packed-refs iterator, and assert on its value.
