Multiple approaches for loading cache data from print page

[FriedrichFroebel]

There currently are two methods which load cache data from the print page: Cache._from_print_page (a class method) and Cache.load_by_guid (a regular method). The first one uses a language-independent approach, while the second one relies on an English page. In the second case there even is a to-do comment to not rely on an English page.

For this reason, we should probably try to reduce the duplicates there and switch to the language-independent approach.

Good idea! The two versions somehow sneaked up into the code over the years.

Proposal: Move the code from _from_print_page to load_by_guid. Then deprecate _from_print_page (it has been marked as internal anyway) and basically redirect to load_by_guid for the deprecation period.
