Checking the emptiness of binNames field before setting into command

[abhilashmandaliya]

• Added check for binNames of all Command to avoid Parameter error when passing an empty array
  • JVM languages like Kotlin treat null and non-null explicitly. To invoke a constructor version of commands that sets the binNames to null, requires a separate if-else code block from the caller site to invoke a desired version of the constructor and, makes code unnecessarily lengthy. However, we can pass an empty array from Kotlin and keep the code cleaner. In the current implementation, it causes a Parameter error.
• Applied minor IDE suggestions
