Remove any spaces at start or end of copied URL/ID

If a user is copying in a link for the template ID or the folder ID from a document, I've seen that they sometimes accidentally include a space at the end which throws an error.

Additionally the error message if the folder ID has a space is (also attached):
Reason: Google Drive Error: The final report could not be uploaded to folder with id '1cxS2x8JufLopQtQIHF_U8_YIc3AC6pC_ '. Possible reasons are a non-existing folder or insufficient permission settings.

This makes the user think that they need to save the report in a different folder when this one should actually work.

I suggest we automatically remove and spaces either at the start or the end of the URL/ID while we are still requires users to provide these.
