Resolving dependencies using Environment Modules fails with galaxy-lib prior to 17.09.9

Issue to track PR #982, which adds a test and bumps the minimum version of galaxy-lib.

## Expected Behavior
Resolving software dependencies using [Environment Modules](
http://modules.sourceforge.net/) should work when the minimum package versions in `setup.py` are respected.

## Actual Behavior
Using any version prior to galaxy-lib 17.09.9 fails, see trace below.
The bug in `resolver_msg` that throws the exception was fixed in [galaxyproject/galaxy@ 69a8700](https://github.com/galaxyproject/galaxy/commit/69a87003f70e3925554fcc88fd2080edab619ed1).

## Workflow Code
```
cwltool \
--beta-dependency-resolvers-configuration tests/test_deps_env_modules_resolvers_conf.yml \
tests/random_lines_modules.cwl tests/random_lines_job.json
```
with *test_deps_env_modules_resolvers_conf.yml* containing
```
- type: modules
```
