Weird logic of numeration for chapters with certain conditions

[Palloxin]

Steps to reproduce

1. Find a novel with a source that doesnt provide the numeration of chapters like this novel
   
2. Switch to "chapter number"
3. Find a chapter who has a number in the title

Expected behavior

The chapters with a number in the title should have Chapter -1 too AND the number is incorrect since it is merely taken from the title due to a bug.

Actual behavior

chapters of entries of sources that dont provide numeration of chapters with (for example) the title "The 8 wonders of Gugu" (so a number in it) are numerated as Chapter 8.

App chapter number parser is not perfect and will never ever be perfect, it can not cover all cases.
Each plugin should provide chapter number to app while parsing novel, if no number found app would use its own parser.
