When I prepare a build node in advance with specific node versions tied to nvm aliases in user Jenkins home, those aliases are not found and used by nvm-wrapper plugin

Set up:

  as user jenkins, nvm install v12.19.0

  as use jenkins nvm alias v12_current v12.19.0

In Jenkins pipeline step, call nvm('v12_current'){....}

Expect:

 plugin looks for .nvm/.nvm.sh in jenkins home dir

  plugin finds that nvm is installed 

  plugin uses v12_current

Find:

 plugin looks where expected

 plugin sees nvm already installed

 directly calling nvm list from sh() shows installed versions and aliases are in fact present

  plugin fails with 'Version 'v12_current' is not found - try `nvm ls-remote` to browse available versions

Why it matters:  preparing versions with aliases minimizes downloads and allows a stable contract sprint to sprint.
