message.data.get("key") leaves in too much vocab

[jrwarwick]

Some simple intent phrases, including example phrases are having some bad parsing resulting in mycroft misunderstanding and failing to attempt correct node names.

In the client debug log:

20:53:31.930 | INFO | 852 | ping-skill | Extracted network node key: send ping to google.com
20:53:31.930 | DEBUG | 852 | ping-skill | k (key) before conditioning: send ping to google.com
20:53:31.931 | DEBUG | 852 | ping-skill | Trying for an ad-hoc DNS name key of sendpingtogoogle.com
20:53:32.056 | INFO | 852 | ping-skill | Requested network node alias not found in hosts.txt registry. Also name resolution failed: Host sendpingtogoogle.com not found: 3(NXDOMAIN)

"send ping to" should have fallen out already, but hasn't.
