Bug 6480 - Koha produces a lot of apache logs for UNIMARC

For Koha with UNIMARC a lot of entries in apache log lines are produced.

In the patch, corrections to the GetCOinSBiblio function has been introduces,
in the UNIMARC section: (i.e. || '' at the end of lines that can create this
problem) -- analogous as it is in the MARC21 section.
