Regarding issue #768: 404 error briefly shown.

Problems: 1. Fix bug where a 404 error is shown on first render.

Solution: 1. Changed from 'any' in initial state to null which was the issue. When rendering it goes in the following order: it goes from top to down, but first all useStates --> everything else --> all useEffects. 'Any' was used before to call a random sensor in earlier patches, but has since been removed and does not work anymore. The initial state could not either be set as, for example "A-Building" since the sensor name could change in the future. Therefore it is set as null and made a return statement in useApi where if no apiurl is entered (null), it will return nothing.
