When i changed my minecraft password. When i restart the minecraft launcher it replaces my old password instead of my new password, so every time i have to write my new password

When i changed my minecraft password. and When i restart the minecraft launcher it replaces my old password instead of my new password, so every time i have to write my new password.

What I expected to happen was...:
that the launcher would not replace my new password with the old password every time i restart the launcher.

What actually happened was...:
the minecraft launcher would not save the new password, and it would replace it with the old password

Steps to Reproduce:
1. Create a new profile in the new launcher and sign-in
2. quit from the launcher
3. change your minecraft password
4. go back to the launcher and replace your old password with the new one and login
5. next time when you run the launcher it will not save your new password and it will try to login with the old one. so every time you should rewritte your password when you restart the launcher
