[Forward-port to 10.0] Cannot enter document names with special characters in document wizard

When creating a document using the document wizard and entering a document name containing special characters, an error is triggered: 'Please specify a valid name'. See also attached screenshot. This can be reproduced in the latest Gogreen.

This error doesn't occur when creating a document from the document perspective, using the regular create document dialog window. In this window, the user can specify both the document name and URL name. When entering a name with special characters, these characters are filtered and no error is triggered.

The expected behaviour for the document wizard is that special characters will be filtered, similarly to the regular create document dialog window.
