When running Job DSL unit tests based on https://github.com/jenkinsci/job-dsl-plugin/wiki/Testing-DSL-Scripts, if we create jobs that contain spaces in the job name the test fails because it can't write config.xml.  This seems to be because the path is being URL encoded (spaces replaced with %20).  If the DSL script replaces the spaces with underscores then the tests pass.

Expected no exception to be thrown, but got 'javaposse.jobdsl.dsl.DslException'
