Fix error Cannot find Builder for algo url name quantiles

[exalate-issue-sync]

Quantiles model is created internally during the training of some other models, but it is not recognized as a regular model and does not have model builder.

When training several models in parallel, and in between calling ModelsHandler.list(), we can hit the situation where the list of models contains the quantiles which leads to the error.

This error was observed by OSS user when using Sparkling Water. Sparkling Water is checking the list of all models before it starts training the model
