check / check (push) Successful in 1m50s
config: watch a target listed twice only once (closes #207)
ClassifyTargets kept a name every time it appeared in DNSWATCHER_TARGETS,
so example.com,Example.com. put example.com in the domain list twice and
every check looked it up and checked its certificates twice, sending two
expiry warnings per TLS check (port checks were already grouped by address
and port). It now skips a name it has already kept, comparing after the
lower-casing and trailing-dot removal it already did; the list keeps the
order of first appearance.
