SD-882 : User is still created as a disabled by default

Changed the code for reset password
When the user is added it is by default active but need activation and
in UI will be shown as pending
"If a user is added it should be already active, so it ca be used to assign tasks to him for example."
Ok, this is a functional specification, we should validate it with PO.
"The sending of email with token is just a easy way to distribute the credentials for a new user."
Actually, this is a security measure.
"After the user is added he also can use forgot password functionality."
This a bit strange as the first password for the account was not set yet and he has the link/email to do so. 
"As already specified an admin can add a user but is not able to set the password (add user has no password related fields) so he don't have a password to log." - far fetched but this can be done with CURL, script or Rest client.
