Dark Vision fails to deploy automatically when the Bluemix space name contains spaces

[l2fprod]

The issue seems to be in Speech to Text. It fails if the callback URL has a space in its name:

{"code":400,"code_description":"Bad Request","error":"unable to register callback url 'https://openwhisk.ng.bluemix.net/api/v1/experimental/web/mail@fr.ibm.com_Game of Bluemix/vision/speechtotext.http', callback server responded with status code 505"}
