TASKMAN-24: Custom created severities/statuses aren't properly displayed when adding a new task

Minor butgeneral note on using quotes in Velocit:
* When you have velocity code that you want rendered in a quoted string, use double quotes: `"Hello, $UserName!"` will render `Hello, Administrator!`
* When you have a plain string with no velocity code inside, use single quotes: `'User Name:'` will render `User Name:`
  * Single quotes can also be used when you explicitly don't want velocity code inside the string to be rendered: `'The variable $doc returns the current context document'` will render `The variable $doc returns the current context document`

Using double quotes everywhere (even where not needed) has a small negative impact on performance because the Velocity rendering engine tries to render all the strings, even the ones that are just plain strings and that should be marked as such.

In your case, `"selected"` is a plain string and should have been `'selected'` instead.
