Duplicate times/tags = duplicate activities

[heymarkreeves]

If two activities are logged with the same start/end time, and the same tags, each activity appears two or more times, depending on number of tags.

To reproduce:

1. Create two activities.
2. Set the start time for both to 8:45
3. Set the end time for both to 9:00
4. Set two tags on both. Example "Billable" and "ClientX"

Each activity will appear twice, with one tag per instance, totalling 4 activities.

But why would you record two activities at the same time?

Because I'm using this to track billable time, and I bill in minimum 15m increments, and sometimes, as in this case with client emails, efforts overlap. If I kick off focused work on a project at 9:00am, I want to accurately capture that using the timer, rather than try to stagger out all my overlapping tasks over the course of the day. I've worked around this by backfilling overlapping activities at staggered times.
