Steps to reproduce:

1. Create a new template in Scroll PDF 3.x with the default settings

2. Update to Scroll PDF 4.7.0 or later

3. Export a page with the previously created deprecated (3.x) template

Expected result:
Title page displays the correct text, for example "Author: <username>"

Actual result:
Title page displays the I18n keys of certain text instead, for example "com.k15t.scroll.pdf.template.default.titlepage.author"

3. After all templates have been updated upgrade back to the latest version of Scroll PDF Exporter.
