[PATCH] Support for the source-map in Karma test framework

Hi Team,

Debugging the failed jasmine test-cases is very difficult with the current
implementation.
The stack-traces does not give the correct information as It does not have
source-map support for the original code.
And, that makes it very difficult to debug the issue during development.

Please attached a patch for adding the support for the source-map in the
karma test framework.

I have also attached another patch, which will definitely fail some of the
test-cases to show the stack-traces of the failed cases.

Please find the output of 'yarn run test:karma-once' before applying the
proposed patch as below:

As you can see, it gives a lot more relevant information in the stack trace.

Please let me know if you have any objection to the proposed patch.
