Steps to replicate the issue (include links if applicable):

• Use Web2Cit's user script to insert a citation which returns source: ["citoid"] from Citoid. For example https://biodiversity.org.au/afd/taxa/Beroe_cucumis, as reported by @MargaretRDonald.

What happens?:

Although both Citoid and Web2Cit citations are shown, the "Zotero & Web2Cit" credit label, including the link to the translation summary page, does not show below.

What should have happened instead?:

A "Powered by Web2Cit" or "Powered by Citoid & Web2Cit" label should be shown.

Software version (skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):

This is probably because the unmodified Cite dialog does not include the credit label when the source returned by Citoid is "citoid":

However, this is important when using the Web2Cit extension, because is the easiest way users have to reach the translation summary page, and edit configuration files.
