Unit test Blueprints v1

[adamziel]

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.
