.btn-link.active shouldn't be box-shadowed

Created by: b1rdex

How to reproduce: <button class="btn btn-link active">test</button> and you got very bad looking box-shadow: inset 0 3px 5px rgba(0, 0, 0, 0.125) on it. Works bad for <a> too. Here is screenshot:

Can be fixed with :none:

.btn.active
   box-shadow: none
   &:not(.btn-link)
     box-shadow: inset 0 3px 5px rgba(0, 0, 0, 0.125)
