The CLI requires developer disk image not only in debug

[DimitarTachev]

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 5.1.0
• Cross-platform modules: 5.1.0
• Android Runtime: 5.1.0
• iOS Runtime: 5.1.0

Describe the bug
When using Sidekick and running iOS apps on Windows, the CLI requires a developer disk image even for run.

Expected behavior
The CLI should require the image only for debug and suggest a manual app start on run.
