Bug 10107 - opacbookbag shouldn't prevent from adding items to a list in the OPAC

This bug is present in master and (at least 3.8.x, where we spotted it).
The patch makes adding items, to a list from the results page, not rely
only on opacbookbag syspref but also 'virtualshelves'.

PS: Thanks Graciela Galli for reporting.

Template only patch, works nicely.
Test plan copied from bug report:

- Disable the opacbookbag syspref
- Login in the OPAC
- Create a list (I tested a private one)
- Search in your db for some biblios.
- Choose some and add them to the created list
- Go to your users's page, to the my lists tab
- Your list is empty.
