Update react-native-quick-crypto to 1.0.18 and remove ECDSA workaround

QuickCrypto 1.0.18 fixes SubtleCrypto ECDSA sign/verify to return IEEE P1363
format as required by the WebCrypto spec (margelo/react-native-quick-crypto#968).
This makes the signEcdsa/verifyEcdsa overrides in ReactNativeCrypto unnecessary
since the base StandardCrypto implementation now works correctly with QuickCrypto's
subtle API.
