Update 'src/app/core/drawers/drawer-manager.js'

Fixed error in "app/core/models/application/actions/action-manager.js!push(action)" during intersection creation due JSON.stringfy
Added header (LInE information) and improved indentation
* batchDraw(): improved, changed "Stages.getCurrentStage().getCurrentKonvaLayer().batchDraw();" by long version
* addAction (action): improved, changed "Stages.getCurrentLayer().actionManager.push(action);" by long version with try/catch
   var currentLayer, actionManager, auxE = ""; try { ... } catch (error) { ... }
