If the work tree's path prefix does not exist in the first of the two trees, then 'got cherrypick' failed with "no such entry found in tree". But this is a legitimate situation, as shown in the new test added here. The first tree could be the empty tree, for example, which should result in 'got cherrypick' adding all files from the second tree instead of complaining about a non-existent path-prefix directory in the first tree.

One part of current behaviour is to delete an unversioned file and replace it with a symlink; that's very bad in case the user wants to keep the file.

This test accepts the current behaviour, even though the current behaviour isn't ideal in some cases.
