[BUG] Default intent is always automatically followed by default intent

[SandraSchufmann]

For bitbot I have defined a default intent i0 and a regular intent ir (among others).

• ir is successfully called whenever I certain things (like "upload") to bitbot.
• i0 is successfully called whenever bitbot doesn't understand what I'm saying.
  Both i0 and ir lead to the same four different new intents i1,i2,i3,i4
• after ir has been understood, bitbot can successfully understand any of i1,i2,i3,i4, depending of what I say to bitbot
• BUT: after i0 has been understood, bitbot always understands the same intent i1 next, no matter what I say
  i1 seems be the automatic default intent for this particular path. So it seems, after the bot has chosen the first default step, it automaticall choses default in the next step as well.
  I've tested this bevahior with other cases and intents and the same thing happened: default is always followed by default.
