coverity#1158232 Fix ownership of NamedDBs::insert argument

f70d03436b7b501e0ed1d745935a204b9b97b855 "coverity#1158232 have a stab at
silencing warning with function markup" claimed that NamedDBs::insert always
takes ownerhip of its argument, but boost::ptr_set::insert(std::auto_ptr<U> x)
simply calls insert(x.release()), so only takes ownership when it returns true.

ScDBDocFunc::AddDBRange (sc/source/ui/docshell/dbdocfun.cxx) relies on this
behavior, deleting the argument when insert failed.

ScDBDocFunc::RenameDBRange (sc/source/ui/docshell/dbdocfun.cxx) relied on this
behavior, deleting the argument when insert failed, until
f55cc330dec0dec60c755e2ce28a840c7fca1956 "Fixed the fallout of the changes in
ScDBCollection" removed the delete (presumably in error?).  I put it back in
now.

All other uses of NamedDBs::insert ignored the return value (witnessed with
SAL_WARN_UNUSED_RESULT).  Some are insert-if-not-found cases, where I added
asserts now (Sc10Import::LoadDataBaseCollection,
sc/source/filter/starcalc/scflt.cxx, is not entirely clear to me, so I added a
TODO), while others would have potentially leaked the argument, in which cases I
fixed the code.
