Issues with filters on admin graphs

Many times I run the report with only “Start Date” set assuming that the end date will automatically be considered as today’s date, but I can understand that it will be more clear/explicit for end user if we automatically fill “End Date” with today’s date. Same applies for start date.

Just pushed a fix for this:

Now the start/end date input on report page will be pre-filled with default date range (a month).
