`as_samples` should handle empty samples
**Description**
`as_samples` fails for empty samples lists.

**Steps To Reproduce**
`dimod.sampleset.as_samples(([], ['a']))`

**Expected Behavior**
Should return an empty sampleset
```
>>> samples, labels = dimod.sampleset.as_samples(([], ['a']))
>>> samples
[]
>>> labels
['a']
```
