Fix dashboard statuses toggling

[julien-nc]

Fix empty php array becoming an array instead of an object when passed to UI. This was preventing statuses state saving if default value was loaded.

Then we don't need to specify the default twice, since it is set below anyways if the default value cannot be parsed.

@juliushaertl Right.

Just to be clear, I think

$statuses = ($statuses && count($statuses) > 0) ? $statuses : ['weather' => true];

is necessary to make sure the case of having '{}' stored in preferences is handled safely.
