--- Issues:
(1) #-2669: Page does not restore to top when navigating new tags.
(2) "Encountered children with the same key" error (duplicate entries shown).
https://github.com/lbryio/lbry-desktop/issues/4367#issuecomment-645449206
--- Changes:
(1) Ignore the history if it's a new query (i.e. explicitly clicked). The BACK history will still behave as normal (doesn't reset to top).
(2) Previously, the `page` variable will continue to increment as you scroll and stay within the page (e.g. Trending vs New, or clicked another Tag). As you move between queries, we hit a scenario where `page` is significantly under or over the latest retrieved `claimSearchResult.length`. This messes up the rest of the code.
Fix by correcting the value of `page` according to the current `claimSearchResult.length` when necessary.
