* internal/target: fix some target tests
We had dupes and missing test cases, this fixes them.
* internal/handlers: move listtoken parsing into helper
This significantly simplifies the parsing logic needed in each handler.
The new design uses four separate service functions; List,
ListPage, ListRefresh and ListRefreshPage. The first two are
used during the initial pagination phase and the latter two
are used for any subsequent refresh phases.
