Fix EmergencyCallTests create dropbox entry test

Update EmergencyCallTests#testEmergencyCallFailureCreatesDropboxEntries
test helper to query dropbox entries based off of
Timeouts#DAYS_BACK_TO_SEARCH_EMERGENCY_DROP_BOX_ENTRIES. Currently, the
test queries entries from the time the test begins running but the
dumpsys includes entries from the (current timestamp - # of days as
defined in the device config [ms]). The test needs to be updated to
ensure we include those entries as part of the verification.
