bug: 0.16.2 asdf plugin update X removes support files

[markjreed]

Describe the Bug

Several plugins populate subdirectories with support files - e.g. nodejs/.node-build, perl/perl-install, python/pyenv. As of version 0.16.2, asdf plugin update is emptying these subdirectories without deleting them, breaking the on-demand population logic – and the plugins.

Steps to Reproduce

1. asdf plugin update nodejs
2. asdf list all nodejs

Expected Behaviour

asdf should display a list of versions available to install

Actual Behaviour

Plugin nodejs's list-all callback script failed with output:
Trying to update node-build... ok
