Remove assertion from PortalRunMulti 
We have an assertion to ensure that a command tag has been assigned by
the time we're done executing, but if we happen to execute a command
with no queries, the assertion would fail.  Per discussion, rather than
contort things to get a tag assigned, just remove the assertion.

Oversight in 2f9661311b.  That commit also retained a comment that
explained logic that had been adjacent to it but diffused into various
places, leaving none apt to keep part of the comment.  Remove that part,
and rewrite what remains for extra clarity.
