Improper concatenation of channel utterances

[chasepeeler]

If the utterance of a custom channel is more than two words, it doesn't concatenate the utterance symbol into a single word, leaving a space in the symbol, which is not allowed.

For example:

{
  utterance_name : 'watch some channel',
  activity: 'Watch DirecTV',
  channel: "516"
}

would create the following:
WatchDirecTVWatchsome channel watch some channel
when it should produce
WatchDirecTVWatchsomechannel watch some channel
