[PATCH v11 18/22] stash: make push -q quiet




There is a change in behaviour with this commit. When there was
no initial commit, the shell version of stash would still display
a message. This commit makes `push` to not display any message if
`--quiet` or `-q` is specified. Add tests for `--quiet`.
