Unique index cannot be created for db table, whose name should be quoted

[Oleg]

It is not possible to create unqiue indexes for tables, whose names should be quoted, for example db_table = 'test-table' .
ORM does not quote index name, so exception is raised:

return Database.Cursor.execute(self, query, params)
E django.db.utils.OperationalError: near "-": syntax error

This was supported in version 1.11 and should be work according to documentation:

If your database table name is an SQL reserved word, or contains characters that aren’t allowed in Python variable names – notably, the hyphen – that’s OK. Django quotes column and table names behind the scenes.
