Usernames with spaces regarded as two usernames

[mats.koponen@…]

When using a username including a space the list will create two items with no email address.

example

'Person 1', 'Some Name', 'some@…'

will make a cc list item as cc: "Person, 1"

When selecting in the autocomplete list it looks OK, but in the saved field of the ticket the error occurs.

In regard to this we have tried to remove the flawed user and added a more correct username 'Person1' for the same email address. I.e. we have tried to cleanup the userslist in htpasswd.

The old user is still present in the autocomplete list as well as the new one.

We would possibly want to rebuild the list used for autocompletion. A reset function or similar whithout resetting the whole database.
