 Give a hint when a TH splice has a bad package key, partially fixes #10279

 Previously, if we got a package key in our splice, we'd give
 a very unhelpful error message saying we couldn't find
 a package 'base-4.7.0.1', despite there being a package with
 that source package ID.  Really, we couldn't find a package with
 that *key*, so clarify, and also tell the user what the real
 package key is.
