We punt from "repair"ing the hash tree during a branch switching if it involves having to create a new tree object that does not yet exist in the object store. "mkdir dir && >dir/file && git add dir" followed by "git checkout" is one example, when a tree that records the state of such "dir/" is not in the object store. However, after discovering that we do not have a tree object that records the state of "dir/", we failed to propagate the fact up the callchain to stop the code to attempt populating the level that has "dir/" as its immediate subdirectory. This led the caller detect and report a non-existent error.
