Fix commit retrieval by tag () ()
Backport 

It is not correct to return tag data when commit data is requested, so
remove the hacky code that overwrote parts of a commit with parts of a
tag.

This fixes commit retrieval by tag for both the latest commit in the UI
and the commit info on tag webhook events.
