garden commands error if there's a broken symlink

[jmeickle]

Bug

Current Behavior

Commands like garden scan fail with errors like this if there's a broken symlink:

ENOENT: no such file or directory, stat '/Users/eronarn/Code/qf/app/assets/javascripts/docs'

In my case:

[eronarn@ip-192-168-10-243 qf]$ ls -lath '/Users/eronarn/Code/qf/app/assets/javascripts/docs'
lrwxr-xr-x 1 eronarn staff 31 Nov 27  2018 /Users/eronarn/Code/qf/app/assets/javascripts/docs -> ../../../qdocs_build/_static/js

The intervening folders exist, but _static doesn't, so the symlink is (currently) broken.

Expected behavior

Local symlink issues don't prevent non-build commands, like scanning the project.

Suggested solution(s)

There should be a warning about the symlink, or potentially the module may fails building if a critical symlink can't be resolved; but project-level commands shouldn't fail on this condition.

Additional context

Usually one would expect symlinks to resolve, but not always; like in this case where I'm working in a repo where I haven't been building the docs. The application would work without the symlink and it's there for developer convenience.
