Show Git history in the History Inspector, even when a remote is not configured

[simonwhitaker]

Description

The previous method of determining the remote URL for a git commit would throw if no remote was configured. This led to the History Inspector panel being empty if the file being edited was under version control with Git but did not have a remote configured.

This PR makes the check for a remote non-fatal if a remote is not configured, setting the remoteURL property of a GitCommit to nil instead.
