fix workspace switching

This fixes #62.

Turns out that when you shadow the `id` parameter but don't provide a new
value in a method call you don't actually end up doing anything.

This commit fixes things by removing the shadowed id so that the `loadCurrentWorkspace()`
method does what it says on the tin.
