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

MigrationRunner.get_current_revision() was creating a SQLite engine without
connect_args={'check_same_thread': False}, causing ProgrammingError when called
from a different thread than the one that created the engine. This is now
consistent with init_or_upgrade() which correctly passes check_same_thread=False
for all SQLite engines.

Added a Behave scenario to verify that get_current_revision() passes
check_same_thread=False when creating a SQLite engine.
