$CWD is used in the lookup of files during mojo run

[Guillermo Gonzalez]

During a mojo if a file is referenced with a relative path in a script the lookup is also done in the current working directoy.

I think it should fail if the relative path is wrong, instead of using the CWD

Steps to reproduce:

1) setup the env
bzr branch lp:~verterok/+junk/test-spec
cd test-spec
# bootstrap a juju env

# create the project
sudo mojo project-new mojo-test-spec -s trusty

# fix perms of lxc
sudo chmod 750 /var/lib/lxc/mojo-test-spec.trusty
sudo chgrp $USER /var/lib/lxc/mojo-test-spec.trusty/
sudo chgrp $USER /var/lib/lxc/mojo-test-spec.trusty

# create the workspace
mojo workspace-new --project mojo-test-spec -s trusty --stage "foo/bar/devel" `bzr root` bug-relative-path

2) error case:
mojo run --project mojo-test-spec --series trusty --stage foo/bar/devel `bzr root` bugs-relative-path

output:

cd foo/bar
