fix(settings): Let email input field scale with the content

[MaxPostema]

partial fix for: #549
It will still need the discussion about using emails. For now we still have non email keys like anonymous and admin to deal with so i wont be changing the input type.

It will still need the discussion about using emails. For now we still have non email keys like anonymous and admin to deal with so i wont be changing the input type.

I propose the final change should have:

• add role select input for 'user' (authenticated users) and 'anonymous' (non-signed in users) => default to 'null'
• replace with email validated input for any other user

[mswertz]

I think this is okay, but you might want to take the step to complete this by adding email validation AND adding seperate role select inputs for the 'anonymous' and 'user' special user groups.

P.S. please also use semantic commit messages. I have now change label to fit
