fix: correct a copy-paste error in a log message (#29)

With the addition of `--banner` option index files no longer start with '// @create-index'

This new regex looks for '// @create-index' that are either at the beginning of the file (old behavior) or if it is followed by a newline.
Basically it just checks whether it exists in a file or not.

Added a test for it now.
