== ISSUE ==
With the new design introduced within Milk, most of the buttons received
a visual upgrade (eg. removing borders)
This change applied on most of the buttons since the same code, but some
buttons were using a `.border` class on top of that and so they did not
loose this border.
== After this commit ==
We clean up these buttons that were keeping a border, in order to make
our secondary buttons more consistent.
Please note that this change does not apply on all secondary buttons
since some of them are customized for a specific module and so remain
unmodified.
