Use qtconsole rather than qtconsole-base.

The conda build test environment uses the requirements in meta.yaml and pip check uses the METADATA in the egg-info populated by this setup.py. However, qtconsole-base shows up in the environment as qtconsole, so pip check doesn't think qtconsole-base is installed.
