[bug] conan asks for password when CONAN_NON_INTERACTIVE=True

This issue surfaced when our artifactory instance slowed down. Most probably the token stored in conan.db expired, and caused this.

password and username are also present in environment.

Environment Details (include every applicable attribute)

• Operating System+version: ubuntu focal
• Compiler+version: n/a
• Conan version: 1.48
• Python version: 3.8

Steps to reproduce (Include if Applicable)

• pull dependencies from remote (authenticate)
• wait for auth token to expire
• try upload with CONAN_NON_INTERACTIVE

Logs (Executed commands with output) (Include/Attach if Applicable)

/usr/local/bin/conan upload MyPackage/1.0 --no-overwrite recipe --all --remote remote --confirm --retry 4 --retry-wait 10

OK, the issue is a false positive, process that ran conan, cleaned up all environment variables, including the non-interaction one

yes, but that is an “out”, that is not a problem, it should not error. But the actual “input”, in input_user, input_password = self._user_io.request_login(remote.name, user) is the thing that is protected by the non-interactive and should raise. The surprising thing is that it is not raising an error.
