Removing Sender Name doesn't work

[murilopereirame]

Describe the bug
When setting the Sender Name to an empty string, the client doesn't return any error or warnings and restore what was set before.

To Reproduce
Steps to reproduce the behavior:

1. Go to Settings > Email
2. Set the "Sender name" to an empty string
3. Click again to change the sender name, see that the data wasn't erased.

Expected behavior
The sender name is empty.

Thanks for your report.

I suspect this is intentional behaviour. Removing the sender name will just display the email address to recipients.

Then the Dialog shouldn't allow saving or it should throw an error. My main concern is that it returns success for an operation that will not be applied
