Pagination erroneously sets `page.title` on homepage (equal to `site.title`)

[marcospgp]

• I am using this package on my Jekyll website, more specifically on the homepage;
• I do not set a title for my homepage (index.html) anywhere in its front matter;
• I do not set a title option in _config.yml pagination settings (also tried explicitly setting to empty string);
• When pagination is disabled, page.title is not set for the homepage, as expected;
• When pagination is enabled, page.title is equal to site.title on the homepage, causing me some trouble.
