The previous test patched api_calls.db_get and pygsheets.authorize then
called those mocks directly—never invoking any cog method. The test
passed even when all cog code was deleted.
Replace with a test that retrieves the real pull_roster_command.callback
from the cog instance, patches dependencies at the correct module-level
names, calls the callback, and asserts ctx.send was called with the
expected error message. If the cog cannot be imported, the test skips
gracefully via pytest.skip.
