wrong min-width generated

Created by: miksh7

When customizing bootstrap (e.g. http://getbootstrap.com/customize/?id=7880081) and setting @screen-md-min = 1280px @screen-lg-min = 1900px @container-md = ((1220px + @grid-gutter-width)) @container-lg = ((1860px + @grid-gutter-width))

it will generate the default @screen-md-min 992px instead of 1280px bootstrap.css (line 700)

@media (min-width: 768px) {
  .container {
    width: 750px;
  }
}
@media (min-width: 992px) {// WRONG
  .container {
    width: 1250px;
  }
}
@media (min-width: 1900px) {
  .container {
    width: 1890px;
  }
}
