Fix the usage of parallel and full options of vacuum command.

Earlier we were inconsistent in allowing the usage of parallel and
full options.  Change it such that we disallow them only when they are
combined in a way that we don't support.

In passing, improve the comments in some of the existing tests of parallel
vacuum.
