Fix since-latest-release + --include-head

[mcmire]

Explanation

The package-level since-latest-release script is useful when authoring release candidate PRs for double-checking that all changes to a package have been properly documented.

Sometimes it is useful to know all of the changes that have occurred for a package, even those that took place on the release branch itself. For this purpose the --include-head argument can be passed to the script, e.g.:

yarn workspace @metamask/assets-controllers run since-latest-release --include-head -- diff

However, this invocation does not work and produces an error instead.

Additionally, if you pass more than one argument after the --, like so:

yarn workspace @metamask/assets-controllers run since-latest-release --include-head -- log -p

then the script freezes and does not continue.

This commit addresses both of these issues.

Manual testing

1. Run yarn workspace @metamask/assets-controllers run since-latest-release --include-head -- diff.
2. The command should give you a diff and not error.
3. Run yarn workspace @metamask/assets-controllers run since-latest-release --include-head -- log -p.
4. The command should give you a list of commits along with diffs and not freeze.
