Reporting server not logging requests when tensorboard is installed.

[peterAsapp]

Describe the bug
If you run the reporting server without tensorboard, you see Flask logs like so:

 * Serving Flask app "flambe.experiment.webapp.app" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://localhost:12345/ (Press CTRL+C to quit)
127.0.0.1 - - [23/Nov/2019 04:50:33] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [23/Nov/2019 04:50:34] "GET /state HTTP/1.1" 200 -

However, if you run the reporting server with tensorboard installed, for some reason, the reporting server stops showing Flask logs.

 * Serving Flask app "flambe.experiment.webapp.app" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off

The reporting server and tensorboard function fine otherwise. However, this is a bit annoying b/c I can't see which port the reporting server runs on if I don't specify it.

To Reproduce

1. Run the reporting server without tensorboard and see all the Flask logging.
2. Install tensorboard
3. Run the reporting server again. Flask doesn't log stuff anymore.

Expected behavior
Flask should log even with tensorboard.
