Description

When running on main-thread (new default since 7.0.0), the "red screen of death" is not shown. This is due to [this commit](https://github.com/appcelerator/titanium_mobile/commit/32dd2c512b18e7cfa6655fb4b57987f45613249a) from the good old 1.x SDK days where we didn't have the ability to run UI on the main-thread. This ticket should also be used to refactor the error dialog a bit - to include the error reason and make a bit less ugly.

PR (master): https://github.com/appcelerator/titanium_mobile/pull/9797 PR (7_1_X): https://github.com/appcelerator/titanium_mobile/pull/9846 Test-Case:

   var win = Ti.UI.createWindow();
   var picker = Titanium.UI.createPicker();
   var rows = [
     Titanium.UI.createPickerRow({
       title: 'Bananas'
     }),
     Titanium.UI.createPickerRow({
       title: 'Strawberries'
     }),
     Titanium.UI.createPickerRow({
       title: 'Mangos'
     }),
     Titanium.UI.createPickerRow({
       title: 'Grapes'
     })
   ];
   picker.add(rows);
   picker.addEventListener('change', function(evt) {
     var column = picker.getColumns()[0];
     column.removeRow(column.rowAt(0));
   });
   
   win.add(picker);
   win.open();

Expected behavior: The "red screen of death" should appear!
