SnappyFrameDecoderTest ByteBuf leak (#9854)

Browse Source 
Motivation:
SnappyFrameDecoderTest has a few tests which fail to close the EmbeddedChannel
and therefore may leak ByteBuf objects.

Modifications:
- Make sure EmbeddedChannel#finishAndReleaseAll() is called in all tests

Result:
No more leaks from SnappyFrameDecoderTest.
