run-tests: obtain replacements inside Test._runcommand
Now that command running is part of Test, we no longer need to pass
a list of replacements down through various call layers.
The impetus for this change is to fetch replacements after
command execution, not before. This will allow replacements to be
defined as part of test execution.
