ENYO-592: fix for inconsistent spotting of paging controls

Issue.

When using paging controls near bounds, some of the paging controls would become activate after the spot has moved to a different container.

Fix.

Update the disable/enable logic, to group controls into two pools, and then enable controls before disabling ones that may be currently spotted.
