[$75] [Metadata Management] keep entered data if error occurs during entity updating

[maxceem]

This is follow up from this comment #3132 (comment) from the similar issue which we fixed during object creation #3132

This issue is valid for all sections in the metadata: Project Templates, Products Templates, Project Types and so on...

Expected behaviour

When we edit any object changed data should persist in the form when a server-side error happens during saving.

Actual behaviour

Updated data is reseted in the form when a server-side error happens during saving.

Steps to reproduce the problem

• Open any page to edit object in the metadata section, for example editing the next Project Template https://connect.topcoder-dev.com/metadata/projectTemplates/207.
• Update any field, for example change name to test
• Click Save button. You would see an error message from the server as the user doesn't have permissions to update the object. The same time the name would be reseted to initial value Subtitle Skills API.
• Expected behaviour is that we should see our changed value when error happens, so we can repeat our attempt to save changed data and don't loose our changes.
