Target: fix read_tree_values for empty dir
grep was existing with 1 when passed an empty directory, resulting in
TargetError being raised unless explicitly suppressed with
check_exit_code=False. This case is now fixed to correctly return an
empty dict without error.
read_tree_values bash function has also been optimized to not
unnecessarily run find in a subshell if the path passed to the function
does not exist.
