Exception is thrown when input component is created in action binding

[dawidkomorowski]

Steps to reproduce:

1. Have InputComponent with action mapping.
2. Bind action that creates new entity with new InputComponent.
3. Trigger action binding.

   Expected result:

   • New entity with InputComponent is created.

     Actual Result:

   • Exception is thrown:

     System.InvalidOperationException
     HResult=0x80131509
     Message=Collection was modified; enumeration operation may not execute.
     Source=System.Private.CoreLib

Acceptance Criteria

• [ ] InputComponent can be created in action binding.

Definition of Done

• [ ] Automated Tests - new and modified code is covered with automated tests
• [ ] Documentation - new and modified APIs are documented
• [ ] Performance - performance is verified to avoid regression
• [ ] Compatibility - consider compatibility of APIs and functionality with previous version and provide upgrade path if possible
• [ ] Demo Application - if new functionality should be showcased in Demo Application or existing functionality changed update Demo Application
• [ ] Release Activities - if release process is affected update Release Activities issue template
