Running ./bin/repository move-paths without specifying --from nor --to
leads to the PHP 8 error about strlen() not accepting null parameters.

Test Plan

Running ./bin/repository move-paths without --from/--to (shows a proper error)

This seems fine, though I wonder if we should introduce a phutil_empty_string() or phutil_is_empty_string function to avoid the double-negative logic. I think this reads more easily:

if (phutil_empty_string($from)) {
  throw new Exception()

than this:

if (!phutil_nonempty_string($from)) {
  throw new Exception()

In the future it may be nice to also have a getArgStr() that always return a string, never NULL. So, we can just if ( $to === '' )
