Many completion snippets insert more than just the name. For example,
the object completer inserts the braces and places your cursor inside
them automatically, to save some typing. However, if you're changing the
class of an existing object, this isn't what you want. Changed so that
if the next token is '{', only the name is inserted.
Made similar changes to the property and signal completers.
