Start does not appear in reports of completed

#### Start column should appear with formatted time

* I ran a custom all report:
```
# in .taskrc
alias.dailywork= start.after:today or end.after:today all
report.all.dateformat=H:N
report.all.columns=start,end,project,description.desc,recur
report.all.labels=Start, Finished, Project, Task, Recurring

# in zsh
task dailywork
```
* I expected to see both start and end times in the report
* The report prints without a start time
I am getting this output:
```
⚑ jess:~/ $ task dailywork

Finished Project Task Recurring
--------- -------- ----------------- ----------
08:20 Task A
18:30 MyLog Task Repeat P1D
07:44 Task B
18:12 Task C
```
**I also found that filter by start does not appear to work as a date**
```
⚑ jess:~/ $ task start.after:socm all
No matches.
```
While,
```
⚑ jess:~/ $ task end.after:socm all
```
prints a list of completed tasks
* Paste the output of the ```task diag``` command.
```
