Original bug title:
UploadWizard should accept redirected template when chosen as license/wikitext

Reproducing:

• https://commons.wikimedia.org/wiki/Special:UploadWizard
• Proceed until Licensing. Select This file is not my own work. -> Another reason not mentioned above -> The license is described by the following wikitext (must contain a valid copyright tag)
• Enter {{CopyrightByWikimedia}}

Result:
"This does not seem to be valid wikitext, or does not contain a license."

Expected:
Very quickly accepted as only one recursion level to [[Category:License tags]]

Version: unspecified
Severity: normal
