fix pagination of location and location type APIs

[czue]

Currently the pagination parameters (e.g. next) of the location apis are always empty. This is because we are improperly setting the resource URI on the list view so tastypie can't render them

The relevant side effect of this is that it's impossible to paginate through locations with the DET which relies on the next param to handle pagination.

if this gets approved could you please also merge it? it's blocking some testing and would like to sneak it into the next deploy if possible (though no need for a special deploy for it)

will merge when tests pass
