Peewee 3.0 update breaking changes

class BaseSignalModel(pw.BaseModel):
change to
class BaseSignalModel(pw.ModelBase):

if cls._meta.db_table and cls._meta.db_table != 'model':
change to
if cls._meta.table_name and cls._meta.table_name != 'model':

Locate the BaseSignalModel definition and the code that reads cls._meta.db_table; compare both references with the Peewee 3.0 names shown in the issue. Update those two compatibility points and run the project's available tests to confirm model setup and table-name handling still work.
