Bug 23502: Staff client "revert status" buttons should not depend on SuspendHoldsIntranet preference

This bug corrects the template logic controlling the display of the
"Revert waiting status" and "Revert transit status" buttons on the staff
client holds page so that it doesn't depend on having
SuspendHoldsIntranet enabled.

To test, apply the patch and locate a title which has multiple holds,
including:

  - One waiting hold
  - One in-transit hold
  - At least one pending hold

View the page with the SuspendHoldsIntranet preference both on and off.
The "Revert transit status" and "Revert waiting status" buttons should
be displayed either way.
