Fix pipeline support and testing for New-GitHubRepositoryFromTemplate (#259)

Added in #221, `New-GitHubRepositoryFromTemplate was not capturing the passed-in value for the RepositoryName if provided via a Uri parameter.

There was a pipeline test in place, however it missed this fact because it was only testing the pipeline input scenario using `-WhatIf`, and the error was only found when calling the actual REST API and GitHub noticed that the `RepositoryName` was missing from the URI.
