Include Wrong-Shelf holds in clear-shelf results

Include non-expired, Wrong-Shelf holds in the results list of the "Clear
Shelf-Expired Holds" process.  ("Wrong-Shelf" holds are those whose
pickup lib was changed while the hold was on the holds shelf).  The idea
behind this option is that branches may use the clear-shelf process as a
general shelf management report beyond just holds that have expired.
I.e. tell me everything I need to remove from the shelf.

This change includes a label change for the clear-shelf menu options:

"Clear Shelf-Expired Holds" -> "Clear Holds Shelf"
