fix(clean_url): encode ^

this is unrelated to address separator of adblock filter syntax
https://adblockplus.org/filter-cheatsheet#blocking1
which does not need to be escaped
uBO can handle this pattern just fine
||example.com/so%5Emany?ca^r=e^t^$all

query string does not need to percent-encode ^,
only pathname
