[Bug] DatepickerSingle causes errors regarding persistend_props to appear in the browser console

[jorickert]

Example code:

from datetime import datetime

import dash
import dash_core_components as dcc
import dash_html_components as html


app = dash.Dash(__name__)

app.layout = html.Div([dcc.DatePickerSingle(id="datepicker", date=datetime.now())])


if __name__ == "__main__":
    app.run_server(debug=True)

Error:
