[Storage] (uploadBrowserDataToBlockBlob should abort when blob < max) - test fails - race condition

[HarshaNalluru]

STORAGE-BLOB

Test from Highlevel test suite failed more than once in Edge browser.

Some sort of race condition, consistently succeeded in the Edge browser when tried to repro.
The same test never failed in the chrome, firefox and IE browsers.

Strangely enough, the console.log for the error caught in the catch block has the "abort" string.

Still, the assertion fails.

Closing this as these failures are over a year old. We now have issues being logged for nightly failures and they will cover the above if these failures are still occuring
