Bug 1735442: Primary buttons in custom theme need border

Before it was transparent, which was fine when header background
colour was dark. But when it is light, eg white, then we can't see
where the button finishes and the page start.

Have made the border the same colour as text of button.

To test: re-save custom theme for institution with some actual change
so system saves new info
