azure-pipelines-tasks: npm install task (not msbuild) fails with EPERM on hosted build

It looks like there are some problems with permissions while installing various packages over npm install.

When I run my build for the 1st time I received the following errors:

npm ERR! Error: EPERM, open 'C:\NPM\Cache\bb33797c-ache-minimatch-2-0-8-package-tgz.lock'
npm ERR! { [Error: EPERM, open 'C:\NPM\Cache\bb33797c-ache-minimatch-2-0-8-package-tgz.lock']
npm ERR! errno: 50,
npm ERR! code: 'EPERM',
npm ERR! path: 'C:\\NPM\\Cache\\bb33797c-ache-minimatch-2-0-8-package-tgz.lock' }
npm ERR! 

After that I just run my build for the 2nd time without any modifications and I got the following errors:

npm ERR! Error: EPERM, open 'C:\NPM\Cache\e360d466-Cache-inherits-2-0-1-package-tgz.lock'
npm ERR! { [Error: EPERM, open 'C:\NPM\Cache\e360d466-Cache-inherits-2-0-1-package-tgz.lock']
npm ERR! errno: 50,
npm ERR! code: 'EPERM',
npm ERR! path: 'C:\\NPM\\Cache\\e360d466-Cache-inherits-2-0-1-package-tgz.lock' }
npm ERR! 

I receiving that errors on VSO
