[User Story] Delete Contact

[florian-papsdorf]

Description

As a user I want to be able to delete a contact, too.

Acceptance criteria (@florian-papsdorf please confirm):

• The contact list shows a delete button/icon/link for each contact
• If I click it, I am asked for confirmation (a simple alert shall suffice)
• If I confirm to delete the contact, the contact is removed from my contact list and the page is reloaded

Dependencies:

• Show accounts in contact list #26 [team-scrumbledores-army, merged, only awaiting customer review]

Implementational tasks:

• write acceptance test (arrange multiple contacts before, act find the delete button for a specific item in the list, assert that the reloaded page does not contain the contact any longer)
• write controller test
• extend controller to provide deletion + confirmation
• extend view to show deletion option
