Crash fix: // do not use the given selection if the plane of the sketch has been already set.
// If this check is absent, a selected plane in the viewer can be set in the sketch
// even if the sketch is built on another plane.
Scenario: show a plane, create sketch, call a line creation, select a plane in the browser(face is selected in the viewer), abort line creation. Result-modification data model outside the transaction. Reason - the sketch is resumed and the selected face is set as the sketch preselection.
