clear all when minlength = 0

[Khanh-Goku]

let minlength = 0
press Ctrl A to select all text
press Delete to clear text

expected: selected-object = null
actual: selected-object does not change

this worked for me...

scope.inputChangeHandler = function(str) {
if (str.length < minlength) {
cancelHttpRequest();
clearResults();
}
else if (str.length === 0 && minlength === 0) {
scope.selectedObject = '';
showAll();
}

    if (scope.inputChanged) {
      str = scope.inputChanged(str);
    }
    return str;
  };scope.inputChangeHandler = function(str) {
    if (str.length < minlength) {
      cancelHttpRequest();
      clearResults();
    }
    else if (str.length === 0 && minlength === 0) {
  scope.selectedObject = ''; //fix
      showAll();
    }

    if (scope.inputChanged) {
      str = scope.inputChanged(str);
    }
    return str;
  };
