Removed no longer used alternative api for surveys/ endpoint.
As bottlenecks in the summary for SR imports are now identified by
their id and no longer by the (not guarantied to be unique!) name,
there is no longer the need to request survey data by the name+date
tuple (which isn't reliable anyway). So the workaround was now
reversed.
