test(bundles): skip uninstall ambiguity test when stdout is a TTY

The non-interactive bail under test only triggers without a TTY; from a
terminal the code correctly opens the interactive selector instead, so
the test hung or failed depending on input. Same guard as the three
sibling non-interactive tests.
