Bug 11246: remove reference to fields 780 and 785 in UNIMARC XSLT files for Bootstrap OPAC

Another fix, 10465, removed fields 780 and 785 from a unimarc xslt file.
This cleanup is needed for bootstrap too

To test : in a UNIMARC Koha, with Bootstrap theme OPAC
1. Be sure that OPACXSLTDetailsDisplay , OPACXSLTResultsDisplay sysprefs
   are set to "default"
2. Apply the patch
3. Search some records in OPAC : the list view and the detail view
   should be exacty the same as before you apply the patch.

Changes are consistent with changes done earlier on the prog theme.
Checked that the detail pages and results still display correctly
for UNIMARC.
