not escaped argument is passed to `git notes add`

[usernam3]

Git notes adapter should escape message before adding it to note MetaCommit::Index::Adapters::GitNotes#write_to_notes

[usernam3]

Tried to use shellwords module but it writes escaped characters to note body, it is not ok. Currently the main problem is double quotes character so I just replaced them in 352b0b3 . It works, but still needs better solution.
