Issue Service crashes when remote extension host failed to launch

[tspence]

• VS Code Version: 1.50
• OS Version: Windows 10 and Mac OSX Catalina

Steps to Reproduce:

1. Connect to a remote server
2. Cause the remote server's extension host to crash, possibly by running out of memory or by killing the process yourself.
3. When the remote server's extension host has crashed, attempt to file a bug by clicking the bug nub icon in the bottom right corner of the main window.

Expected Result:

• Issue reporter window appears and allows user to file a bug

Actual Result:

• Issue reporter window fails to launch. If you check the debugger, you will see that an exception stack trace for "ExtensionManagementService.getInstalled".
• Since the remote extension host is not active, getInstalled() doesn't work - it throws an exception rather than returning an empty list.

Does this issue occur when all extensions are disabled?: Yes
