EvalSymlinks in Contains() check

git's root command (maybe others vcs as well) resolve symlinks, so try
that too.

PS: In git's case we can possible use rev-parse --show-cdup + extra
logic to find the root of the repo instead. Need to figure out what
other vcs root commands do as well.

Fixes #339
