Japanese Lorem sentences look unnatural

[rastamhadi]

Describe the bug

In the Japanese locale, Faker::Lorem.sentence, Faker::Lorem.sentences, Faker::Lorem.paragraph and Faker::Lorem.paragraphs produce strings with:

1. Spaces in between words
2. Spaces in between sentences

Natural Japanese text includes neither of these spaces.

e.g. https://ja.wikipedia.org/wiki/%E3%83%86%E3%82%B9%E3%83%88%E3%83%87%E3%83%BC%E3%82%BF

To Reproduce

irb(main):001:0> I18n.locale = :ja
=> :ja
irb(main):002:0> Faker::Lorem.paragraph
=> "いう 日没 電話。　がいよう 当て字 シアトルし。　フランス人 あくれい 弱虫。"

Expected behavior

Japanese sentences without spaces.

irb(main):002:0> Faker::Lorem.paragraph
=> "いう日没電話。がいよう当て字シアトルし。フランス人あくれい弱虫。"

Solved in #1918, so I'm going to go ahead and close this. Thank you @koic @vbrazo @Zeragamba
