shelve: use colon instead of quotes in 'changes to' description

If detailed conflict markers are enabled and the closing quote gets truncated,
editors will often screw syntax highlighting up from that point because they'll
see an opening quote and think it's the beginning of a string.

In tests, the hashes change because the commit messages of the shelved bundles
also change.
