[kio_http] Parse a FullyEncoded QUrl path with TolerantMode
When using url.setPath(otherUrl.path(FullyEncoded)), we have to specify the TolerantMode parsing mode (setPath uses DecodedMode by default), otherwise we end up with a doubly encoded url:
otherUrl.path(FullyEncoded) would represent a space as %20 then url.setPath(otherUrl.path(FullyEncoded), DecodedMode) would represent the '%' character with '%25' so the path ends up with '%2520'.
AFAIU, either we use: url.setPath(otherUrl.path(FullyDecoded), DecodedMode) OR url.setPath(otherUrl.path(FullyEncoded), TolerantMode)
url.path() and url.setPath use FullyDecoded and DecodedMode by default, respectively.
Thanks to Andreas Schwab for figuring it out in the bug report.
