fixup #remove functionEntry and revert e15e32fdb7d515b

- forgot to use readList in removeEntry, which caused the test failure.

- remaining problem:

it doesn't work as might be expected
This is the problem:

dict
{
   foo xxx;
   bar yyy;
}

dict
{
   baz zzz;
   #remove foo
}

This only removes 'foo' from the current scope (the second dict), since
it occurs before the dictionary merge does.

To remove from the final, merged dictionary, we'd need a new
deleteEntry type that would do the right thing on the merge before
self-destructing (ie, removing itself too).
