Don't override the deblocking setting in the encoder test

Since this is on by default now, we don't need a separate test
that has it enabled. Thus we can now remove one of the encoder
tests.

By not overriding the deblocking setting at all, the hash
changes for the other tests that use SEncParamExt.
