Row deselect fix when md-select-id is supplied

[Panicsystem]

When deselecting a row (removing from the 'selected' array), if the md-select-id is supplied, use this instead of an object search.

This prevents a wrong deselect behavior when:

• Pull your list
• Select some rows
• Refresh/Update the list via http
• Deselect a row, the objects references have been changed, the wrong row is deselected.
