rename test case to better describe error

[alightgoesout]

After removing the requirements to have spaces before node children (#499), I feel like test cases brackets_in_bare_id_fail.kdl is poorly named.

foo123{bar}foo weeee

This test should still fail, but for different reasons. The name suggest foo123{bar}foo is not a valid identifier, but it should now be parsed as foo123 { bar }. It fails because there are no node separator between the first node and the second one (foo weeee).

I have looked and found no test that check a similar case, so I have renamed the test case to semicolon_after_children_fail.kdl, but feel free to suggest other names.

This sounds completely reasonable, but I think the name still sounds misleading. ^_^ Perhaps semicolon_missing_after_children_fail?

Yes, you're right. I have renamed the file accordingly.
