Fix patient count expectation in PDS match rate test

The test was incorrectly expecting only 4 patients to be created when the
import is above the PDS match rate threshold. However, the setup creates
10 changesets total (7 with PDS matches + 3 without), and there are 4
changesets from the uplaoded CSV so when the import passes validation,
all 14 should be processed and create patient records.
