Vscode: debugging 'continue' shortcut stopped working, tries to relaunch debugging task

• VSCode Version: 1.39.0-insider, 9f6a745027fc7b2a12495970f64625e24f410224
• OS Version: Darwin x64 16.7.0

Steps to Reproduce:

1. Using f5 to cause vscode to run a debug session on a test in my project using the following config.

{
    "type": "node",
    "request": "launch",
    "name": "Mocha Current",
    "program": "${workspaceFolder}/node_modules/mocha/bin/_mocha",
    "args": ["${file}", "--timeout", "999999", ],
    "internalConsoleOptions": "openOnSessionStart"
}

1. stop on a breakpoint, previously pressing f5 would cause the continue command to be executed, and the breakpoint to be released. Now I'm just getting an error There is already a debug configuration "Mocha Current" running. and the breakpoint remains as is. I did not change any of the keyboard shortcuts, and see both actions (start debugging and continue) bound to f5

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