<p-auto-complete> behaves differently than <p-autocomplete>

[hunhejj]

Describe the bug

I assumed that <p-autocomplete> and <p-auto-complete> are interchangeable, the output is the same. However that's not true, because there are some stylings explicitly added for p-autocomplete but not for p-auto-complete. An example is for that is the invalid state as showcased in this Stackblitz demo.
