Display prefecture after Dojo name (instead of region name)

[yasulab]

Fix #380

This PR changes the following 2 things:

1. Display prefecture name instead of region name:

• Delete hard-coded region name in /db/dojos.yaml
• Display prefecture name after Dojo name

2. Records in DB:

• Change records in Prefecture model like this:
  • 北海道 -> 北海道
  • 東京都 -> 東京
  • 大阪府 -> 大阪
  • 沖縄県 -> 沖縄

Sorry for replying so late.
Why do we need this commit ac0215c ?
It seems unnecessary for the purpose of this PR.

It seems unnecessary for the purpose of this PR.

@nalabjp Yeah, I thought this not necessary, but through creating this PR I needed to update some of dojo names as noted at ## 2. Records in DB. And I found this changed the order of dojo listing. So I put this code to set order by ascending.

But what I care about is the order and result, so if the order and result is same as now, I'm not against to deleting this code. ;)

@yasulab
Thank you for your easy explanation.
I believe that orders in prefectures are already collateralized.
That's because Dojo.default_order scope is applied to the return value of the following code.

coderdojo.jp/app/controllers/home_controller.rb

Line 4 in ae8da6c

@regions_and_dojos = Dojo.group_by_region_on_active

coderdojo.jp/app/models/dojo.rb

Line 13 in ae8da6c

scope :default_order, -> { order(prefecture_id: :asc, order: :asc) }

So, I think that Dojo' default_scope can be deleted, but what do you think?
