Improve Automation Scripting carret movement

-> Autocompletion box do not toggle as expected;
Write "Document." close suggestion, or miss, move caret after "." try to open suggestion box... It is no more usable.

-> Autocompleted script are not indented properly

-> On a suggestion; "CMD + arrow" move the carret to the begin of the Operation instead of the beginning of the line as expected.

-> Following default JS formatting rules; generated operation should look like to:

Document.Delete(input, {
  'hello': 'asdsad',
  'asdasd': 'asdasd'
});

instead of:

Document.Delete(
input, {
}
);
