Storage: Do not throw for path containing ".."

[hsubox76]

Based on the only reference to ".." in the Android repo (a test), it seems we do not try to parse ".." as a parent shortcut on the client side and just pass it directly to the server. (https://github.com/firebase/firebase-android-sdk/blob/d7017614307c4497f5b91da3c59b6de2102a17b7/firebase-storage/src/test/java/com/google/firebase/storage/PathingTest.java#L162)

So we will just remove the error and the test for it, and server errors should enable developers to debug if they pass an invalid path.

Fixes #5180
