#1679: fix determine version if npm list has exit code 1

[hohwille]

This PR fixes #1679

Implemented changes:

• do not fail if npm list gives exit code 1 (for tool not installed) since this seems normal in npm.
• added method ProcessContext.withExitCodeAcceptor
• use that method in NpmBasedCommandlet
• added method ProcessContext.createChild()
• use that method for ToolInstallRequest so we do not disable default exit code handling for parent tool installations
• extended test

Labeled as internal since the ticket was already added to CHANGELOG by PR #1680
