Fix #10638 : makes remove return correct list when used with both --queue and -A (#10641)

* fixed a bug where using both `--queue` and `-A` would yield a "removed" list without the queued experiments

* added a test to validate the fix

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* clearer name for test
