Added to tests for the revoke access to a view API call
(DELETE /banks/BANK_ID/accounts/ACCOUNT_ID/users/USER_ID/views/VIEW_ID)

The scenarios were:
- revoke access to a random user
- revoke access to a view that does not exist
- revoke access to a user but without enough rights
Fixed problem with default user (tesobe@tsobe.com)
fixed a bug keeping the Privilege Admin button hidden even if the user can access to the page
1) implemented the following API calls with their corresponding tests:
  - GET /banks/BANK_ID/accounts/ACCOUNT_ID/VIEW_ID/other_accounts
  - GET /banks/BANK_ID/accounts/ACCOUNT_ID/VIEW_ID/other_accounts/OTHER_ACCOUNT_ID
  - GET /banks/BANK_ID/accounts/ACCOUNT_ID/VIEW_ID/other_accounts/OTHER_ACCOUNT_ID/metadata
  - GET /banks/BANK_ID/accounts/ACCOUNT_ID/VIEW_ID/other_accounts/OTHER_ACCOUNT_ID/public_alias
  - POST /banks/BANK_ID/accounts/ACCOUNT_ID/VIEW_ID/other_accounts/OTHER_ACCOUNT_ID/public_alias
  - GET /banks/BANK_ID/accounts/ACCOUNT_ID/VIEW_ID/other_accounts/OTHER_ACCOUNT_ID/private_alias
  - POST /banks/BANK_ID/accounts/ACCOUNT_ID/VIEW_ID/other_accounts/OTHER_ACCOUNT_ID/private_alias

1) Refactored the project files to delete useless traits.
2) Since the files became much more sorter, I grouped most
of the classes together into fews files.
3) Delete the Management view form the permittedViews function
because the Sofi application has a different layout for this page.
