response ending in 2 newlines leads to empty message

[erohmensing]

If you define your response using the +| format in YAML,

  utter_newline:
    - text: |+
          This is one part of my response:  
          
          Something 
          Something else

  utter_other:
...

the representation of this automatically ends in \n\n. However since we split based on those characters, you end up with an empty message, e.g. in the rest channel:

[
  {
    “recipient_id”: “test1",
    “text”: “This is one part of my response:  ”
  },
  {
    “recipient_id”: “test1",
    “text”: “Something  \n20910 Something else”
  },
  {
    “recipient_id”: “test1",
    “text”: “”
  }
]
