conda build --test incorrectly reports 'All tests passed' for non-existent package files

What happened?

When running conda build --test with a non-existent package pattern, it incorrectly reports "All tests passed" instead of failing:

(base)  swap357@Swapnils-MacBook-Pro  ~/test  ls                                                         
(base)  swap357@Swapnils-MacBook-Pro  ~/test  /bin/zsh -c "conda build --test 'fake_package_name*.conda'"
All tests passed
(base)  swap357@Swapnils-MacBook-Pro  ~/test  /bin/bash -c "conda build --test 'fake_package_name*.conda'"
All tests passed
(base)  swap357@Swapnils-MacBook-Pro  ~/test  /bin/zsh -c "conda build --test fake_package_name*.conda"  
zsh:1: no matches found: fake_package_name*.conda
(base)  ✘ swap357@Swapnils-MacBook-Pro  ~/test  /bin/bash -c "conda build --test fake_package_name*.conda"
All tests passed

This was tested with zsh and bash, and enabling debug mode (--debug) shows no additional useful information.

(base)  swap357@Swapnils-MacBook-Pro  ~/test  ls
(base)  swap357@Swapnils-MacBook-Pro  ~/test  /bin/zsh -c "conda build --test --debug 'llvmlite*.conda'"
DEBUG conda.gateways.logging:set_log_level(221): log_level set to 10
All tests passed
(base)  swap357@Swapnils-MacBook-Pro  ~/test  /bin/bash -c "conda build --test --debug 'llvmlite*.conda'"
DEBUG conda.gateways.logging:set_log_level(221): log_level set to 10
All tests passed

What should have happened instead?

According to the help documentation, --test requires "a path to built package file". When no valid package file is found:

• The command should fail with an error indicating no matching package files were found
• It should not report "All tests passed" when no tests were actually run
