test(modules): fix favicon_test checkMatchers arity after matchers-condition (#228)

#189 added the condition param to checkMatchers; the favicon matcher test
(#183) still called the 3-arg form, breaking the build once both landed.
pass "" (default and-condition) to restore single-matcher semantics.
