More helpful error messages

Traceback (most recent call last):
  File "/Users/andersh/Projects/moz-sql-parser/tests/test_simple.py", line 113, in test_bad_select1
    self.assertRaises('Expected select', lambda: parse("se1ect A, B, C from dual"))
  File "/Users/andersh/Projects/moz-sql-parser/venv/lib/python2.7/site-packages/mo_testing/fuzzytestcase.py", line 69, in assertRaises

  File "/Users/andersh/Projects/moz-sql-parser/venv/lib/python2.7/site-packages/mo_logs/__init__.py", line 398, in error
    raise e
Except: ERROR: expecting an exception returning "Expected select" got something else instead

That's a deeply unhelpful message. You should print what that "something else" is.

Thank you for this. I copied this issue to moz-sql-parser, who is responsible for the poor message.
