show route in both directions in AVL report

[wkulesza]

Expected functionality
When viewing AVL reports, it would be handy to display routes in both directions. Similarly as in maps view, each route is printed in both directions.

Describe the bug
Currently, when you open an AVL report and select a route and generate report, you can see markers of vehicle but also stops and shape for one direction. Agencies use this feature to indicate to passengers that their bus stopped at a stop and if there's no route in opposite direction visible, agency can't generate a screenshot with that case.

To Reproduce
Open up AVL reports, optionally select vehicle, set other options, choose desired route from dropdown and hit Generate Report.

Screenshots
This screenshot shows that route is showed only in one direction.
