Instead of the LEFT JOIN were we hoped we would get proper results we are now using a sorted subselect that does the right thing everywhere.

Turns out the fix is no good. The subselect only fetches the absolute last start_time no matter the MAC so it only fits for one MAC and the rest of the rows are empty.

The subselect with a LIMIT 1 only worked for a single record and not the entire node view so it had to be reverted. Any other attempts I made in that direction were either too slow or incorrect.

I settled on a solution that involves not always having the last_... information by joining when end_time is null. This makes sure that the locationlog is always accurate at the cost of losing the information on closed entries.
