[BUG] ngi_user_info.yml not updating correctly

[Olzeke51]

Description

voiced Neon that my first name is Gary.
Could never get a response from Neon.
nmi_user_info.yml added some stuff to my name

Steps to Reproduce

fresh install of 7.5b40, voiced my location, voiced my timezone
later did a voiced 'my first name is Gary'
when queried - got no response -- by voice or mana.....
edited miscellaneous characters in my name
Works Now.....

Relevant Code

this is the original::

(venv) neon@neon:~$ cat .config/neon/ngi_user_info.yml
user:
  first_name: ''
  middle_name: ''
  last_name: ''

this is the modified by voice: [extra stuff after 'Gary'

(venv) neon@neon:~$ cat .config/neon/ngi_user_info.yml
user:
  first_name: Gary . "   <<< this is what voice input created,
                         <<< could not get a voice/txt answer 
                         <<< 'what is my first name' 
                         **** did get an answer to 'my location' !!!!
  middle_name: ''
  last_name: ''
  preferred_name: ''
  full_name: Gary . "
  dob: YYYY/MM/DD

It looks like STT in this case added punctuation which usually shouldn't happen. Two places we could handle this:

1. In the personal skill, clean any non-alpha characters from the configured name
2. In the user-settings skill, clean any non-alpha characters before saving the recorded name to configuration

My inclination is to normalize things going INTO configuration, but checking it here could also help catch weird configuration values since that can be changed outside of the settings skill too
