Let's unit test the following Blueprint steps that don't have any unit tests yet:

• defineSiteUrl
• exportWxr
• exportWxz
• importFile
• importWordPressFiles
• mkdir
• request
• runWpInstallationWizard
• setPhpIniEntry
• rmdir
• unzip
• writeFile
• zipWpContent

In addition, some steps (like installTheme) are tested through runBlueprintSteps and not with a direct call – let's explore simplifying that and using direct calls instead.
