MDEV-26504 THD::copy_db_to() fails to return true if THD::db is null
THD::copy_db_to(): Always return true if the output parameter
was left uninitialized. This fixes a regression that was caused
by commit 7d0d934ca642e485b2c008727dc20c83e26cce10 (MDEV-16473).
MariaDB Server 10.3 and later were unaffected by this bug
thanks to commit a7e352b54ddfaf91c92951d605cb02a4ffd2676b.
Possibly this bug only affects mysql_list_fields()
in the Embedded Server (libmysqld).
This bug was found by GCC 11.2.0 in CMAKE_BUILD_TYPE=RelWithDebInfo.
