fix: [#4325] Skip Storage properties from BotState class

[sw-joelmut]

Fixes #4325

Description

This PR fixes an issue where the Host calls a Skill using the BeginSkill action, and right after ending the conversation with the skill a TextInput is prompt.
Moreover, after the input was prompted and provided the text response, the Host fails, because it tries to call the Skill again.
Furthermore, the Host was trying to call the Skill because the ConversationState was being updated with old information due to the BeginSkill class was saving into the Storage the ConversationIdFactory and ConversationState instances (that also have a Storage).
By skipping the two properties, like DotNet does, solved the issue.

Specific Changes

• Added a functionality to skip properties into the BotState class, iterating the state object properties to find and skip the desired properties from outside the BotState scope, to then compare them in the hash functionality.
• Added the skip properties functionality into the BeginSkill.beginDialog method.
• Added two unit tests to address the BotState and BeginSkill changes.

Testing

The following image shows the comparison between the DotNet's Storage saved information and the one used in JavaScript.
