http_proxy: fix the User-Agent inclusion in CONNECT
It should not refer to the uagent string that is allocated and created for the end server http request, as that pointer may be cleared on subsequent CONNECT requests. Added test case 1184 to verify. Reported-by: T200proX7 on github Fixes #7705 Closes #7707
