Added extra except clause to TryRemoveIndex

I have been experiencing the following issue, when using django-celery-results with SQLite:

pysqlite3.dbapi2.OperationalError: no such index: django_cele_group_i_299b0d_idx

It appears the following except clause does not catch the pysqlite OperationError:

class TryRemoveIndex(migrations.RemoveIndex):
    """Operation to remove the Index
    without reintroducing it on reverting the migration
    """

    def database_forwards(self, *args, **kwargs):
