fix: respect correctly hmr: false from command's dashed options

NativeScript CLI doesn't respect correctly `hmr: false` when the option is provided through dashed options from command. This led to the exception when the application is built using CLI and deployed on device using Xcode as the `hmr` is included in app's bundle.

Fixes:
#4846
#4814
