What's in this PR?

There are 5 tests using deprecated test annotations and although they are not an issue right now, they are quite annoying when you are working with the library development. This PR replaces the deprecated annotations with the proper assertions.

1) Http\Client\Socket\Tests\SocketHttpClientTest::testNoRemote
The @expectedException, @expectedExceptionCode, @expectedExceptionMessage, and @expectedExceptionMessageRegExp annotations are deprecated. They will be removed in PHPUnit 9. Refactor your test to use expectException(), expectExceptionCode(), expectExceptionMessage(), or expectExceptionMessageMatches() instead.

2) Http\Client\Socket\Tests\SocketHttpClientTest::testBrokenSocket
The @expectedException, @expectedExceptionCode, @expectedExceptionMessage, and @expectedExceptionMessageRegExp annotations are deprecated. They will be removed in PHPUnit 9. Refactor your test to use expectException(), expectExceptionCode(), expectExceptionMessage(), or expectExceptionMessageMatches() instead.

3) Http\Client\Socket\Tests\SocketHttpClientTest::testNetworkExceptionOnConnectError
The @expectedException, @expectedExceptionCode, @expectedExceptionMessage, and @expectedExceptionMessageRegExp annotations are deprecated. They will be removed in PHPUnit 9. Refactor your test to use expectException(), expectExceptionCode(), expectExceptionMessage(), or expectExceptionMessageMatches() instead.

4) Http\Client\Socket\Tests\SocketHttpClientTest::testNetworkExceptionOnSslError
The @expectedException, @expectedExceptionCode, @expectedExceptionMessage, and @expectedExceptionMessageRegExp annotations are deprecated. They will be removed in PHPUnit 9. Refactor your test to use expectException(), expectExceptionCode(), expectExceptionMessage(), or expectExceptionMessageMatches() instead.

5) Http\Client\Socket\Tests\StreamTest::testTimeout
The @expectedException, @expectedExceptionCode, @expectedExceptionMessage, and @expectedExceptionMessageRegExp annotations are deprecated. They will be removed in PHPUnit 9. Refactor your test to use expectException(), expectExceptionCode(), expectExceptionMessage(), or expectExceptionMessageMatches() instead.

Why?

Why not?

Checklist

• Updated CHANGELOG.md to describe BC breaks / deprecations | new feature | bugfix
• Documentation pull request created (if not simply a bugfix)

^ This PR does not change the library itself and I could not find anything like that on the CHANGELOG.md, therefore I have updated it nor documented it anywhere else to be honest.

Thanks for this and you others PR, i want to move to github actions first (so we can be sure that tests are ok) before merging this, but got no time ATM to do that, will merge later then.

thanks for the contribution! sorry that this went under. meanwhile, the exception expectation is converted to assertions.
