Prior to this commit, if no tests were found when running unittest discover
then nothing at all was written to stdout, leading one to think it's not
working at all. CPython unittest does display a "0 tests run" sort of
output in such a case, and this commit ensures this package does the same.
This is not included by default in most builds, and isn't necessary for
this module anyway.
Also fix the local variable shadowing the traceback module in _capture_exc.
Added test for both (works on CPython and MicroPython).
Version bump to 0.10.2.

This allows a much more natural way of implementing unitttest-discover:
- unittest provides unittest/__init__.py
- unittest-discover provides unittest/__main__.py
It also fixes an bug where unittest.py previously detected the presence of
unittest-discover.py by importing an checking for the ImportError. But that
could also be raised by a missing dependency. Now when you run
`micropython -m unittest` without unittest-discover, you get
`ImportError: no module named 'unittest.__main__'`, and without the
required deps, `ImportError: no module named 'argparse'`.
