test(artifacts): write the storyboard fixture's action in Cocoa syntax

MacFixture.storyboard declared its button action with the iOS attribute,
<action selector="buildTapped:" destination="vc1">. Cocoa documents
name an action's receiver with target=. ibtool compiled the iOS spelling
into an NSNibControlConnector whose NSSource is the view controller
placeholder and whose NSDestination is the button. That is the reverse
of what Xcode-authored AppKit NIBs contain (Music, Chess,
KeepingYouAwake, and Transmission all archive NSSource as the control),
and it is what the old inversion had matched. With target= the compiled
fixture archives the button as NSSource. The temporary connector dump is
removed; the observed routes remain in the assertion message.
