ghq does not work well with multiple ghq.root with nonexistent directory

[znz]

Recent ghq does not work with multiple ghq.root with nonexistent directory.

I use first ghq.root only. Second ghq.root for ghq list after I use go get.

I don't know which ghq version does not work.
At least, old ghq works well.

environment:
macOS Mojave and install ghq using homebrew

% sw_vers
ProductName:	Mac OS X
ProductVersion:	10.14.4

% brew info ghq

% git config --get-all ghq.root

% ghq --version
ghq version 0.12.1 (rev:)

expected:
ghq get https://github.com/motemen/ghq clone to ~/s/github.com/motemen/ghq.

actual:

% ghq get https://github.com/motemen/ghq
     error lstat /Users/kazu/g/src: no such file or directory

I found ghq list does not work too.

%  ghq list
     error failed to filter repos while walkLocalRepositories(repo): lstat /Users/kazu/g/src: no such file or directory

This behavior changed after #60 is merged.

I made this change because I thought it would be better to raise the error clearer than to ignore if the directory doesn't exist.

However, it may be better to create automatically when we ghq get. Even in the case of ghq list, it is possible to specify a relative path such as ./vendor in GHQ_ROOT, so it may be better not to raise an error after listing the primary root.

Thank you for your explanation.
I understand changing behavior.
So I create the directory or unset nonexistent directory from ghq.root.
