[muranoPL] Class method 'initialize()' is not executed if object created in muranoPl code with command 'new'

[Dmytro Dovbii]

1. Create a simple class:

Namespaces:
  =: io.murano.apps.simple
  ...

Name: SimpleClass

Extends: std:Application

Properties:
  name:
    Contract: $.string().notNull()

Methods:
  initialize:
    Body:
      - $._someVar: 'hello'

  deploy:
    Body:
      - $this.find(std:Environment).reporter.report($this, $._someVar)

2. Create instance of class SimpleClass somewhere in another code

$simpleObj: new(SimpleClass, name => 'testApp')

3. Try to execute method deploy() of created instance:

$simpleObj.deploy()

4. You'll see an exception:

"Access to uninitialized property _someVar in class io.murano.apps.simple.SimpleClass is forbidden"

It means that method 'initialize()' has't been executed.
