To produce this situation
sign in as [email protected]
Click on Distributions, then "All Distribuitons"
type "nov 08 to feb 08" in the date range box and hit return
You currently get a 500 error
We should instead display an error "date range not properly formatted."

Some things just use a helper, but some others are more complicated.

Criteria for completion

• range formatting errors handled on all the screens that use date ranges
• tests to support this behaviour
