Revert "fix django1.5 syntax changed for base list views (WIP)"

This reverts commit 07ae9fdceed6ae638fbbe75a4ec88a0d1c4336e2.

Squash the two and force-push?
de-lint arm_wells view tests
add test: QuerySetBackedWellView has well in context
add failing test: queryset view has object_list in context

the MultipleObjectMixin is supposed to do this, but it isn't. Other
context variables the mixin is supposed to provide are: paginator,
pag_obj, and is_paginated.
fix queryset view was missing object_list in context
