Fix os.tmpDir() deprecation warning in WebKit Developer Tools Console

[osya]

In the WebKit Developer Tools Console there is a DeprecationWarning: os.tmpDir() is deprecated. Use os.tmpdir() instead. There are some corresponding issues:

• DeprecationWarning in Developer Tools
• os.tmpDir() is deprecated. Use os.tmpdir() instead
• [Extension Host] (node:9908) DeprecationWarning: os.tmpDir() is deprecated. Use os.tmpdir() instead.

All these issues are closed and recommended to search the root cause in VS Code extensions. I searched through source code of my installed extensions but can't find tmpDir there. Then I found that vscode-python (and probably some other VS Code extensions) uses old vscode-extension-telemetry (v. 0.0.5) which uses old version of applocationinsights (v. 0.15.6), which uses os.tmpDir() in Sender.js. I changed version of vscode-extension-telemetryto 0.0.14, which usesapplocationinsights1.0.1, which usesos.tmpdir()inSender.js`.

I launched it and it seems worked. It is not tested because there are many issues with tests in this repository

Unfortunately we are close to the release of a new version sand are at code freeze. Will merge this for the next release. Thanks

One thing I'd check if said extension version matches vscode 1.18 listed in dependencies (rather than the latest). We don't normally require latest vscode since users don't always upgrade VSC immediately.
