Add forgotten cleanup of fairway dimensions
This is actually a fixup of rev. e21cbb9768a2, that added database
schema version 1431 with a constraint trigger preventing new or
updated rows to have a duplicate area but missed to cleanup existing
data. So cleanup now, before the duplicates hurt in future imports
that try to keep the duplicates in history.
