Settings update visual bug

[t-aleksander]

Describe the bug When an input field is updated and the save button is clicked in the "global settings" menu in defguard core, the previous value appears in the place of the new one, after refreshing the page, the correct value (the new one) is displayed but nonetheless it looks confusing.

To Reproduce Steps to reproduce the behavior:

1. Change the instance name or login logo url in the global settings menu
2. Click save
3. Your new value disappears
4. The previous value appears in the input field
5. After refreshing the page, the input has the correct, new value

Expected behavior Saving settings shouldn't visually revert input values.

Version information Reproduced on our dev instance, which currently is on the external openid login branch.
