fix(framework): property with empty object as default value

[nnaydenow]

Properties with type: Object that don't have specified default value in their declaration decorator have {} as default value.

This {} is stored in the initial state of the component and its reference is shared between instanced.

Same apply for multiple properties but with [] instead of {}

In some cases where the property value is changed with an index instead of a new reference, the component starts to behave wrongly because the value of the shared reference is changed.

this.propertyName.somethingNested = "Some new value"

With this change, we provide a new object reference whether the default value of the property is accessed
