Bug 7720: (follow-up) fix issues in Bootstrap theme

- Fix breakage of tablesorting when OpacLocationBranchToDisplay
  is set to both.
- When displaying the home library, ensure that its correct
  name and URL are displayed
- Remove the attempt to display the "opac_info" tooltip for
  the home library, as it is not currently retrieved.

RM NOTE: Rather than add a GetOpacInfo function or the like
to the TT Branches plugin, simpler would be adding a
plugin function that fetches a DBIC result object for
a given branchcode, thereby allowing any column in the
branches table to be fetched into the template.
