// Update() function. We need a user object in updateTaskLabels to check if the user has the right to see
// the label it is currently adding. To do this, we'll need to update the webhandler to let it pass the current
// user object (like it's already the case with the create method). However when we change it, that'll break
// a lot of existing code which we'll then need to refactor.
// This is why.

// We also set this here to prevent it being overwritten later on.
//t.Labels = ot.Labels
// For whatever reason, xorm dont detect if done is updated, so we need to update this every time by hand
// Which is why we merge the actual task struct with the one we got from the
// The user struct overrides values in the actual one.
