tests: Catch vim errors in read_buffer

Browse source 
Without this, TestInfoActionNotTriggeredByEnterOnLink would pass because
it asserts that the buffer is empty, which is what read_buffer returned
if vim was stuck showing an error message. With `PYTEST_FLAGS=-s`, it
would additionally log

    E449: Invalid expression received: Send expression failed.

but that's easy to miss.
