Use LongURL.org to expand (a.k.a. unshorten) URLs that have been shortened using some URL shortening service (such as bit.ly, t.co, or goo.gl).
Pick a URL from your draft from the list, and it will be sent to LongURL.org for expansion. Then long-press the expanded URL to copy it to the clipboard.
Note: LongURL.org does not accept short URLs that are longer than 50 characters.
