Fix leak in SniClientTest. (#8324)

Browse Source 
Motivation:

We need to release the ReferenceCountedSslContext to eliminate resource leaks.

Reported in https://garage.netty.io/teamcity/viewLog.html?buildId=33353&buildTypeId=netty_build_oraclejdk8&tab=buildLog#_focus=157264.

Modifications:

Call release on the SslContext instances.

Result:

No more leaks in tests.
