Made StreamSocketTest and StreamSocketClientTest extend from LunrBaseTest instead of PHPUnit framework directly.
The following files are related to the above and therefore their methods have been updated, where useful.
StreamSocketBaseTest
StreamSocketClientBaseTest
StreamSocketClientFlagsTest
StreamSocketClientHandleTest
StreamSocketClientReadWriteTest
StreamSocketClientTest
StreamSocketContextTest
StreamSocketSetGetTest
StreamSocketStateTest
StreamSocketTest
