Title: [remind] Filter empty strings from the message

This fixes a problem with the .in command where not all of the arguments for the
duration get applied.

With the example command, you end a with a message containing:
```python
['3h', '', '45m', 'Go to class']
```
That empty string there makes the following loop terminate before it gets to '45m'.
