runInTerminal reverse-request missing cwd key

According to the DAP specification, the cwd key in the runInTerminal request is mandatory.

https://microsoft.github.io/debug-adapter-protocol/specification#Reverse_Requests_RunInTerminal

however, the java debug server sends the request without this key:

2018-12-20 00:03:04,861 - DEBUG - Message received: {'command': 'runInTerminal', 'arguments': {'kind': 'integrated', 'title': 'Java Debug Console', 'args': ['/Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home/jre/bin/java', '-agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=localhost:53159', '-Dfile.encoding=UTF-8', '-cp', '/Users/ben/.vim/bundle/vimspector/support/test/java/test_project/target/classes', 'com.vimspector.test.TestApplication', 'hello', 'world!']}, 'seq': 2, 'type': 'request'}

of course, clients could work around this, but it would be nice for the server to include the required parameter.

首先定位构造 DAP 反向请求 runInTerminal 的 Java 调试服务器代码，然后将其参数与链接的 DAP 规范进行比较。当请求包含必需的 cwd 键，并且相关的请求行为由项目的测试覆盖时，工作即完成。
