when putting in wrong npm name

• it opens konsole with error
• it will not return to any usable state, "working..." forever
• even closing and redoing will not work, just sais command failed
• test outside the happy path

• [x] can still click the button even in working state will create async tasks that will fail

• [x] show errors to user / log: cables-gl/cables/issues/6661
• [x] fails if node-gyp and path has a space: cables-gl/cables/issues/6657 (see: https://github.com/nodejs/node-gyp/issues/65)
• [x] fails when packaged and no precompiled binaries: cables-gl/cables/issues/6621
• [x] fails when mixing import/require in packages and subpackages: cables-gl/cables_electron/issues/145
• [x] npm install prunes files, so suggesting to run in terminal to install is moot: cables-gl/cables_electron/issues/145
