Gazr does not handle forecast elements

[majassow]

When using gazr the following elements do not get duplicated:

['dashboard_elements', 0, 'query', 'analysis_config'],
( { 'forecasting': [ { 'field_name': 'ip_reuse.distinct_product_ip_configs',
'forecast_interval': 'month',
'forecast_n': 24,
'seasonality': 12}]
