1657282: fix redirect of one-hit metarecord searches
This patches fixes a bug where, when performing a metarecord
("Group Formats and Editions") search, one-hit result sets
get redirected to a "/eg/opac/record/0.0..." page, which
results in a "Bad Request" error being shown to the user.
To test:
[1] Perform a metarecord search that would result in exactly
one metarecord search. Observe that the browser displays
a "Bad Request" error page.
[2] Apply the patch and perform step 1 again. This time, the
search should succeed. Note that if the metarecord contains
more than one component, a results page with one grouped
hit is displayed; if the metarecord has exactly one component,
that bib's record page is displayed.
