TileConditions: Avoid copying AttributeList.

Copying a coral::AttributeList is not thread-safe. Change AthenaAttributeList::coralList() to return a reference rather than making a copy.

Disable thread-safety checking for the unit test (to prepare for adding warnings about unsafe uses of AttributeList).
