Upgrade message.position to message.place; remove stray console.log

[oscarlevin]

This gets rid of the ts warnings about message.position. It also removes that extra console.log that spit out messages.

Thanks!

In trying to eliminate another type warning at file, I discovered that there are two different VFile imports. Some (in the pretext conversion package) are from "vfile" and others are from "unified-lint-rule/lib". Changing them all to the latter fixes the type error, but introduces other errors. Is there an advantage to cleaning this up? Any prefference?

All imports should be from the same place (and we should keep all versions in sync). If you want to switch so that everybody uses a newer vfile, that would be great!
