e2e test invocation script passes even if test fails

[surajssd]

This is leading to false positives. See logs of run from https://semaphoreci.com/cdrage/kedge/branches/pull-request-297/builds/6

Script says it passed even if the e2e test failed:

@ashetty1 do you mind looking at this?

[ashetty1]

@surajssd the customvol tests have succeeded and have been marked as PASS, while --- FAIL: Test_Integration/Normal_Wordpress_test has FAILed. What exactly needs to be investigated?

[surajssd]

@ashetty1 the tests failed, but still the test invocation script exits with status 0, rather it should also fail!
