test: ensure presets are evaluated in order

Browse Source 
This tests to make sure that preset patterns are checked in the order
they were declared. Both "prefix-1.service" and "prefix-2.service" match
against two rules: their exact name (which enables the service) and
"prefix-*.service" (which disables the service). Because of the
ordering, only "prefix-1.service" should be enabled.
