Undeployment of handler function is blocked until all the handler functions deployed

• Deploy 3 handler functions, this is sequential in nature
• Wait till first handler got deployed, once its deployed then undeploy it
• you will see handler code in http://10.142.170.104:8091/_p/event/getDeployedApps
• Delete handler code and refresh

Observed :- Handler code is not getting deleted from UI unless all the remaining handler code is getting deployed.
