FileRepo.list() throws NPE if the repo directory has been deleted

[njbartlett]

NPE occurs because File.list() returns null on a non-existing directory. Should either handle this and throw a better exception, or return empty list.

Hmm, the root directory is checked in the construction of the plugin. I've fixed it but wonder how this could happen. I think it can only happen if the repo was deleted?

[njbartlett]

Yes the repo was deleted. It was a user error but it should be handled more smoothly

ok, in latest release
