Container prefix and caret are shown in different lines

Issue type: bug report

**Python version: 2.7
**NetBox version: 2.1.0

In /ipam/prefix, the right caret and the container prefix are shown in different lines. Adding style "white-space: no-wrap" to span inside should fix it.

I'm not able to recreate this. If the page is less than a certain width, the table should scroll horizontally.

It seems to happen only in Google Chrome. I couldn't recreate in Firefox.

Up to 767px screen width it works fine. For wider screens, the white-space: nowrap is removed due the media query below and the line breaks.

@media screen and (max-width: 767px)

white-space: nowrap;
}
