[Bug]: `bal profile` does not works with a service

[rdulmina]

Description

In the offifial guid https://ballerina.io/learn/ballerina-profiler/#profile-a-ballerina-service it demonstraigt how to profile a ballerina service. But it gives

curl: (7) Failed to connect to localhost port 8080 after 0 ms: Couldn't connect to server wso2@Dulmina Documents % curl localhost:8080/covid19/countries/names

Seems the ballerina service is on hold or teminated after running.

We need to add proper test cases after fixing this
