Automate endpoint miqButtons fix

Avoid DOM id conflict by prefixing AE endpoint selection buttons.

@h-kataria, please, review

Original report: When editing a new dialog in the dialog editor, add a new dialog, add tab, then box then try to add a field. Add button is NOT enabled for you.

The reason for this was a duplicit DOM id, so it may work for someone in some browser, sometime, but will not work for someone else depending on which of the conflicting DOM elements gets updated.
