DB-dependent tests moved

Moved test cases that depend on the DBMS and having
an initialized Koha database to a subdirectory
of t so that they will not be swept up into
the default 'make test'.  Goal is to have
these DB-dependent tests runnable either via
a special make target or perhaps from the
web installer.
