[TASK] History template: Restyle CSV Export button

RT-2384

- Make the History page's Date/Description/Export to CSV button the same
design and spacing as the Contacts page's Contacts/Ripple name or
Address/Add contact button

- Make sure that when you go between the two pages, the "Add contact"
button and "Export to CSV" button doesn't "jump" around. This means
moving the "Export to CSV" button to the right.
