Make commit log relative to release branch

[samouri]

summary

np provides a mechanism for specifying a release branch other than master. Notably main is a popular one. Am I correct in thinking that the current "Commit Log" generated will always be relative to master regardless of release branch?

Please let me know if I'm misunderstanding anything.
If this fix generally looks good, I'd be happy to add tests.

We need to pick main or master automatically depending on whether they exist. I think we should add a utility to git-util.js called defaultBranch, that infers the default branch based on a simple heuristic, by checking in this order main, master, gh-pages. This utility could potentially be used here too:

np/source/git-util.js

Line 58 in c43c6cf

const allowedBranches = releaseBranch ? [releaseBranch] : ['main', 'master'];

For some reason running npm test keeps freezing at a message claiming "prerequisite checks". Do you have any advice on how I can verify this change works?

Can you fix the merge conflict?

Can you fix the merge conflict?

Done!

I'm still concerned about this though.

The current code crashes when you run np. Please manually test np after each change. The unit tests cannot catch everything.

The changes look good now, the error was being caused by a wrong import. I tried out the functionality as well and it looks it is working relative to release branch.
