Show raw target in redirect editor

Description of the Change

Always show raw input value in the Redirect To field in individual rule edit screen. Previously it was set to show url uncoded value once it is saved which used to make it inconvenient for further edit.

Closes #201

How to test the Change

• Edit individual redirect rule
• Put some special characters in Redirect to field
• Save and reload the editor
• It still should show the exact value entered previously
