Trim the text fields in the add user form before submitting

Describe the bug
Currently, when creating a new user if we have any trailing spaces the form doesn't accept it saying it's invalid.

To Reproduce
Steps to reproduce the behaviour:

1. Go to users
2. Click on add new user
3. Edit the text fields and add trailing spaces.
4. Click on submit
5. See error

Expected behavior
The text fields must automatically get trimmed before submitting.
