Continuos error log when analytics dashboard is idle

[nuwand]

Description:

When I have a session timed out analytics dashboard open on the browser, the follow error log is printed once every minute on the dashboard server logs

ERROR {org.wso2.analytics.apim.idp.client.ApimIdPClient} - Unable to get access token for the request with grant type : 'refresh_token', for the user 'null'.

This results in the following error log on the API Manager server logs

ERROR - OAuth2Service Error while finding application state for application with client_id: null

Unnecessary ERROR logs cause system monitoring tools to trigger alerts, causing panic.
