Create action button does not display the "+" icon

[Lin Hua Cheng]

If the Create table actions is created using tables.Action like:

class CreateEndpoint(tables.Action):
    name = "create_endpoint"
    verbose_name = _("Create Endpoint")
    requires_input = False
    classes = ("show-spinner", "btn-create", )

The "+" icon does not show up.

If the class tables.LinkAction is used, it works fine.

The problem is in the horizon.less:

 a.btn-create, a.btn-launch {
      .btn-icon(-403px, -92px);
    }

It only works <a>, but not <button> which is rendered when tables.Action is used.
