Fix tokens list pagination

[vbaranov]

Motivation

• Some tokens are missing on the 2nd page of bridged tokens list
• Numeration of the items starts with 1 on every page (tokens list, bridged tokens list, addresses list)

Changelog

• Fix pagination query filtering by ordered token name
• Add items count on the previous pages in the query for the next page to account it in numeration
