Import should not change the file name if it includes spaces

Current Situation

• Assume that a file name for import to the inventory contains a space.
• Assume that the import will fail as there is some invalid JSON document in the file.
• In this situation the import popup window displays the error.
• When clicking the Import button once again then the file name is changed: Example:

  import%25252525201.zip
  

Desired Behavior

• The file name of the import file should not be changed.
