Description of the Issue

If you have macros saved, and delete one, the "Run macro multiple times" dialog box still contains the macro name in the dropdown/combo box. This causes the index of any macro "after" that to be off by 1.
If you restart notepad-plus-plus, this is corrected.

Steps to Reproduce the Issue

1. Save 3 macros.
2. Delete the 1st macro.
3. Open the "Run a Macro Multiple Times Dialog. (The deleted macro will still be there)
4. Run the "Second" (should now be first but the bug leaves it there) Macro. This will actually run the third macro because the combo box says run macro index 1.

Expected Behavior

Deleted macros not to show up in the dialog box.
