Martin von Zweigbergk b8f71a4b30 working_copy: in LockedWorkingCopy::drop(), discard unsaved changes
In `LockedWorkingCopy::drop()`, we panic if the caller had not called
`finish()`. IIRC, the idea was both to find bugs where we forgot to
call `finish()` and to prevent continuing with a modified
`WorkingCopy` instance. I don't think the former has been a problem in
practice. It has been a problem in practice to call `discard()` to
avoid the panic, though. To address that, we can make the `Drop`
implementation discard the changes (forcing a reload of the state if
the working copy is accessed again).

Hint: Increase the value of the `snapshot.max-new-file-size` config option if you
want this file to be snapshotted. Otherwise add it to your `.gitignore` file.
