simple_sheduler_example does not work as expected

[StashaS]

Expected:

1. Run the simple_sheduler_example example.
2. Example displays text with "duck answer" three times during three minutes.

Actual result:

1. Run the simple_sheduler_example example.
2. Displayed line OK. I've added a task to say to the duck that you're hungry every day.
3. App waits for 3 min with no other lines displayed.

Bug:

1. Displayed line contain "every day", when initial request for saying "each minute".
2. [Cannot actually reproduce now, every response contains something about a daily task] Even if initial prompt changed to "every 10 seconds" and first line contains "every 10 seconds", no futher lines appears.
