Fix "AphrontRequest->getRequestURI()" for requests with "x[]=1" parameters in the URI
Summary:
Ref T13250. See PHI1069. This is a small fix for `getRequestURI()` currently not working if the request includes "x[]=..." PHP-flavored array parameters, beacause they're parsed into arrays by `$_GET` and `setQueryParams(...)` no longer accepts nonscalars.
Instead, just parse the raw request URI.
Test Plan: Visited `/search/hovercard/?phids[]=X`, no more fatal. Dumped the resulting URI, saw it had the right value. Tried `?phids[]=x&x=1&x=1&x=1`, saw the parameters correctly preserved.
