fix(database/migration_runner): add check_same_thread=False to get_current_revision() SQLite engine

Pass connect_args={"check_same_thread": False} when creating a SQLite engine
in get_current_revision(), consistent with init_or_upgrade() which already
applies this setting for all SQLite engines. Without this fix, calling
get_current_revision() from a different thread than the one that created
the engine raises a ProgrammingError.
