The ordering did not actually change, but the test was failing because
it was throwing away the preset terms.. preset.terms() actually returns
translated terms not original terms, and should default to returning the
original terms when translations are not available (like in testing).
taginfo’s relation/wiki_pages method no longer places results in a data property.
Also, only use relation/wiki_pages for top-level relation presets. More specific presets behave like non-relation presets. For example, the bicycle route relation has the tags type=route route=bicycle, so route=bicycle is what we’re interested in.
Fixes#3297.
