Query .clean_terms deletes all results of a query when there are 3 or fewer results

[malandrina]

The following script returns an empty array:

spanish_dictionary = Dictionary.new('enes')
moonlight_in_spanish = spanish_dictionary.query('moonlight')
moonlight_in_spanish.results

This is because Query.clean_terms currently removes 3 elements from the results, even if there are only 3 or fewer results.

The JSON response to the above query looks like this:

"term0" : {
"PrincipalTranslations" : {
    "0" :{
        "OriginalTerm" : { "term" : "moonlight", "POS" : "n", "sense" : "light of the moon", "usage" : ""},
