lp1373203: Allow users to escape metarecord holds (backport version)

Provides a means for users to escape a metarecord hold if they accidentally
clicked the Advanced Hold Options link. A "Go Back" link will be
provided to allow the user to return to a title hold. If the hold starts as a
metarecord hold, this link won't display since we don't know which bib the
patron wants.

Also fixes an issue where the hold cancel button always returned the user to
the previous screen.
