Fixed "-on today" option inclusive date parsing

It's a one line fix, basically when the parsed date is parsed from the CALENDAR I force time to end of day if inclusive is set.

Ran the behave tests and works, also ran some jrnl live tests checking behavior:

``` bash
jrnl(ontoday)$ jrnl -on today
