[LanguageModel] Return top languages only with a reasonable sample set

[LanguageModel] Return top languages only with a reasonable sample set

Before, the LanguageModel returned top languages even if it had only one
data point. Thus the frequencies of top languages could change
drastically in the warm-up phase of the model.

This CL adds a minimum size of the sample set. The model returns empty
list of top languages before this minimal size is reached.

Looks good, but it seems you need to update the unittest as well.
