test 3: MIN-AGE+VISIT-CAP CRITERIA MET

1. zero visits > {browser.history_expire_days}
2. some visits > {browser.history_expire_days_min}
   AND total visited sites count > {browser.history_expire_sites}

steps:
  - clear history
  - reset observer
  - add a visit, 2 days old
  - add a visit, 2 days old
  - set browser.history_expire_days to 3
  - set browser.history_expire_days_min to 1
  - set browser.history_expire_sites to 1
  - kick off incremental expiration

confirmation:
  - check onPageExpired, confirm our visit was expired
  - query for the visit, confirm it's not there
