sendText sends command twice in new terminals during onDidChangeTerminalShellIntegration

Testing #208462

In my onDidChangeTerminalShellIntegration handler, I have the following line:
e.terminal.sendText('echo "Hello shell integration!"', true);

I notice that when I start my extension, a terminal is already open, and text is not sent to that terminal. Whenever I start another terminal, I notice that the command is placed into the terminal twice and is run each time.

If I change the true to false, I notice that text is still not sent to the already-open terminal, but that for new terminals, the text is pasted in twice as well, so I get echo "Hello shell integration!"echo "Hello shell integration!" in the new terminal.

This is actually by design, when the shell isn't ready to accept input it just echos the text. The first text is the echoed text, the second is the actual input
