Revert "steam-http: fixed requests randomly hanging"

This reverts commit 8223e6ba3382017d70d102b68b0fe2135bd270af.
Fixed relogon operations not resending failed requests

When a relogon request is sent and processes successfully, the requests
that failed are not resent correctly. This is noticeable with polling
requests as they are never reinitiated. As a result, the polling loop
comes to an end which leads to no messages being retrieved. Moreover,
this kills the logon session, and eventually the user will appear
offline. Additionally, queued messages fail to resend correctly.
