handling memory error in timeout utility

[Blind4Basics]

• removed the use of test.expect_no_error inside the timeout utility:

  • done "manually", allowing to handle data passed to the thread
  • consequence: DOCS need an update because there isn't any extra assertion anymore, now.

• tested on cw with 3.6, 3.8 wihtout imports, 3.8 with imports: work as expected.

• removed a comment in the framework about the timeout (deprecated info)

• added the default message for timeout ssertion (https://github.com/codewars/python-test-framework/issues/4)

~~Still need to upddate the tests output (and maybe the tests files)~~ done => trying to pass the outputs checks... XD

@kazk: the tests are fucking slow to run... I bet this PR will still have troubles about the expected outputs, but if you can already take a look...?

I'll try again to offer the possibility to wrap blocks with the timetout utility while avoiding the assertion outside any test.it block, but that will be for another PR.

I don't get it... :/

exception isn't raised, apparently, while it's there in the test file. The memory crash is even weirder, because the exact same code is behaving as expected in a kumite... :/

Bed time, now. Cheers
