Update test folder structure for standalone JasmineRunner test to work as well as e2e script

[kood1]

The e2e-script works with the current test folder structure, with browserResponse.txt file being inside of msl-client-browser folder. However, if someone follows the getting started doc and opens JasmineSpecRunner.html, the last test fails because of invalid file path to browserResponse.txt. We should create a new folder within "test" and make standalone Jasmine runner and e2e work accordingly.

Suggested path: test/responseFiles/browserResponse.txt
