SERVER-19402 Change find command semantics for sorting on an array field.
This eliminates the behavior in which the lowest-valued
in-bounds index key was chosen as the sort key. After this
change, we instead choose the lowest key overall, which may
or may not be in-bounds. This change prevents the sort order
from depending on either the query predicate or the
implementation details of the query planner.
Note that it is no longer correct for a multikey index to
provide a sort over an array field. However, a non-array
field of a multikey index can provide a sort when that index
has path-level multikeyness metadata.
