Add missing StartTransaction for ToggleSelectedVisibility

[dhiraj-143r]

Closes #3381

This PR fixes issue #3381, where hiding/unhiding a layer did not always update the document's saved state correctly.

The issue was that the ToggleSelectedVisibility action did not start a transaction.

This only seems to work if I hide the layer and then also select it, can you please double-check if the solution you implemented works on your end and addresses the original issues? We will look at the code once the functionality is complete
