GCS server does not handle requests with port, and simply report an
error:
```xml
<?xml version="1.0"?>
<?xml version='1.0' encoding='UTF-8'?>
<Error>
<Code>InvalidURI</Code>
<Message>Couldn't parse the specified URI.</Message>
<Details>Invalid URL: storage.googleapis.com:443/...</Details>
</Error>
```
Removing the port fixes the issue. Note that there is port in the Host
header anyway.
Note, this is a problem only for proxy in a tunnel mode, since only it
sends such requests, other sends requests directly via HTTP methods.

This use-after-free can be reproduced with distributed queries.
Also note, that this is not sumMappedArray() and friends (that
previously called sumMap()) but Map combinator.
You will find ASan report in details.
