Bug 561 api keys issues missing org_token_permissions

[johnpinto1]

Fixes # 561.

These changes were suggested by @briri . Will fix tests next week.

Changes proposed in this PR:
On save or update of an Org that is managed we add all the
token_permission_types for API access using a before_save callback.

NOTE: The Super Admin will need to go to Edit Org page and save (with no changes) for the token_permission_types to be added.

Test:

• I have tested this by finding an Org that was managed and did not have token_permission_types set.
• As Super Admin I went to Edit Org page and saved.
• Then I checked if token_permission_types were set and they were.
• Furthermore, I could make API calls now.

Here is the test on my local docker rails console.

irb(main):029:0> f1000 = Org.where(name: "F1000")[0]

Before editing Org
irb(main):031:0> f1000.token_permission_types
TokenPermissionType Load (1.1ms) SELECT "token_permission_types".* FROM "token_permission_types" INNER JOIN "org_token_permissions" ON "token_permission_types"."id" = "org_token_permissions"."token_permission_type_id" WHERE "org_token_permissions"."org_id" = $1 LIMIT $2 [["org_id", 1071570973], ["LIMIT", 11]]
=> #<ActiveRecord::Associations::CollectionProxy []> <---- (NO org_token_permissions for Org)

After editing Org
irb(main):032:0> f1000.token_permission_types
TokenPermissionType Load (1.7ms) SELECT "token_permission_types".* FROM "token_permission_types" INNER JOIN "org_token_permissions" ON "token_permission_types"."id" = "org_token_permissions"."token_permission_type_id" WHERE "org_token_permissions"."org_id" = $1 LIMIT $2 [["org_id", 1071570973], ["LIMIT", 11]]
