predict doesn't return file name where predictions are stored
**Running:**

from a2ml import A2ML, Context

ctx = Context()
a2ml = A2ML(ctx, 'auger, azure')
ret = a2ml.deploy(model_id='A7663CC9C3324B3',locally=True, provider='auger')
print('ret: ', ret)
ret = a2ml.predict(filename='../iris.csv',
  model_id='A7663CC9C3324B3', locally=True, provider='auger')
print('ret: ', ret)

**Output:**
ret:  {'auger': {'result': True, 'data': {'model_id': 'A7663CC9C3324B3'}}}
ret:  {'auger': {'result': True, 'data': {'predicted': '/Users/vtrv101/Projects/dplrn/test/predictions/'}}}

**predicted doesn't contain file name** 

**Environment Details:**
 - OS: macOS
 - A2ML Version: 0.5.0.dev0
 - Python Version: 3.7.6
