Messages that have the 'Repeated' suffix lead to name clashing with the generated Repeated aliases

The following code won't compile because of name clashing:

message MyMessage {
    int32 a = 1;
}

message MyMessageRepeated {
    repeated MyMessage b = 1;
}

MyMessage generates the QList alias that is handy in certain usecases and blocks the usage of Repeated suffix in MyMessageRepeated.

We should avoid generating aliases.
