imap: set cselect_bits to CURL_CSELECT_IN initially
... when continuing a transfer from a FETCH response. When the size of the file was small enough that the entirety of the transfer happens in a single go and schannel buffers holds the entire data. However, it wasn't completely read in Curl_pp_readresp since a line break was found before that could happen. So, by the time we are in imap_state_fetch_resp - there's data in buffers that needs to be read via Curl_read but nothing to read from the socket. After we setup a transfer (Curl_setup_transfer), curl just waits on the socket state to change - which doesn't happen since no new data ever comes. Closes #5961
