Do not open project on error

[karchjd]

If path does not exist, no project is created, but it is still attempted to open the project. This change fixes this.

When building for testing, a new rstantools-package.Rd was created which was not in sync anymore with the .R file.

Pull request overview

This PR fixes a bug where rstan_create_package() would attempt to open a non-existent RStudio project when the directory already exists. Additionally, it synchronizes the auto-generated package documentation with the maintainer email specified in the DESCRIPTION file.

• Moved the file.exists(path) check before the on.exit() call to prevent opening a project when directory creation fails
• Updated maintainer email in auto-generated documentation to match DESCRIPTION file (jgabry@gmail.com)
