If an exception occurs during handling another exception we were
getting a useless traceback such as the following, after which
BitBake froze:

ERROR: Command execution failed: Traceback (most recent call last):
  File "/home/user/poky/poky/bitbake/lib/bb/command.py", line 84, in runAsyncCommand
  File "/home/user/poky/poky/bitbake/lib/bb/cooker.py", line 1207, in updateCache
    if not self.parser.parse_next():
  File "/home/user/poky/poky/bitbake/lib/bb/cooker.py", line 1694, in parse_next
    logger.error('Unable to parse %s', value.recipe,
AttributeError: 'exceptions.TypeError' object has no attribute 'recipe'

Fix this to print an actual traceback of the exception and exit
gracefully (well, as gracefully as possible under the circumstances).

The general fix for [YOCTO #2977].
