Fix 'default' on non-visible choice symbols

Previously, 'default CHOICE_SYM [if <cond>]' in a choice would skip any
following 'default' properties if <cond> was non-'n'. However, those
other defaults should still be considered if CHOICE_SYM has visibility
'n'. Previously, we'd immediately fall back to selecting the first
visible symbol in the choice in that case.

get_selection_from_defaults() now exactly mirrors sym_choice_default()
from the C implementation, and got less convoluted too.

Nothing in the kernel defconfigs triggered this.

Add a new test case too.
