Bug 27538: fix correlation of fields in Holds to Pull table

Bottom filtering row of "Holds to pull" table do not correlate to other
ones, columns diverged from "Call numbers" cell: it should be under
"Available call numbers" while it's under "Available barcodes", and so
on to the last cell (while number of cells still adjusted).

To reproduce:
   1) Head to the Holds to Pull page, check that bottom filtering row
      shifted to the left by one, starting from the "Call number"
      column and don't correlate to the upper table (for example, "Call
      numbers" cell should be under "Available call numbers" while it's
      under "Available barcodes"), and so on for all cells till the end
      of the filtering row.
   2) Apply patch.
   3) Refresh Holds to Pull page and ensure that all filtering row
      columns correlate to other rows columns correctly.
