Use commit `title` instead of `initial version` for initial `spr` message

[justinbaltazar]

Use the actual commit title instead of [𝘀𝗽𝗿] initial version for the initial spr message. This is useful for instances where you are working in a repository with commit linting.

For example, if the repository requires that the first commit of each code change has a JIRA ticket in the commit message, the lint rule will fail.

@spacedentist Do you see any issues with this PR?

This should be configurable though.
