Unable to set user name and email

[Zsailer]

Description

(Huge thanks to @jzhang20133 for finding the root cause of this issue—I'm merely reporting her findings :))

We noticed a regression from previous versions of this package.

When initializing a repo, if the user name and email is not set, the extension no longer raises a modal prompting a user for name/email. Instead, it raises an error dialog to the user:

The root of the issue appears related to related to: #1294

There is one more place where we should explicitly check if path == null:

jupyterlab-git/src/components/GitPanel.tsx

Line 845 in b878c0b

if (!path) {

When we make this change, the prompt appears:

Reproduce

The easiest way to trigger this issue is to remove any git config that sets the user's email or name. Then, turn off git's "auto-detection" for user details/email.

git config --unset user.name
git config --unset user.email

git config --local user.useConfigOnly true

After adding these settings, use jupyterlab-git to make an commit and you'll see the error mentioned above.

Expected behavior

Prompt the user for a user name and email if not set.
