Fix user mention processing

When mentioning a user, the markup post-processor did not handle the
case where the mentioned user did not exist well: it tried to skip to
the next node, which in turn, ended up skipping the rest of the line.

To fix this, lets skip just the mentioned, but non-existing user, and
continue processing the current node from there.

Fixes #3535.
