SimpleCombo/Combo shows invalid state after disabling a touched form control

[Timmeeeey]

Description

Calling control.disable() on a reactive FormControl bound to an igx-simple-combo (or igx-combo) flips the combo's visual state to IgxInputState.INVALID (red error border) — even though a disabled control should never render as invalid. This happens whenever the control has been touched or is dirty.
