EntityHub: Fix label issues in entity hub

[iLLiCiTiT]

Changelog Description

Entities don't have changes when entity is fetched and "label" and "name" have same values.

Additional review information

In case name and label are same the label should be set to None but because server returns "label" with value same as name it causes that the entity have changes: {"label": None}.

Testing notes:

1. Prepare task or folder that has same label as name.
2. Use EntityHub to get the entity.
3. The entity should have empty changes attribute value.
