Remove spaces in the MDR entities' and attributes' fields of name and uniqueName

[cbeach47]

Describe the issue
Currently, the MDR UI allows spaces in the JSON Name and UniqueName for MDR entities and attributes, and quite a few entries (Entity and Attribute) have spaces in their Name and/or UniqueName.

This ticket is to remove all spaces in the Entity and Attribute tables' Name and UniqueName columns.

Additional context
#801 will remove the ability to add spaces in the UX.

Looks like spaces in the source entity name and source attribute name affect users.
