Don't clear headers on redirect (#5973)

Browse Source 
Current implementation clears _headers when request was sent. If the
user added custom request headers, they will be lost and the redirected
request will not contain them. This commit changes the scope of cleanup
so that the headers survive redirects but don't survive connection
reuse.
