Manually cleanup token stream when macro expansion aborts.

In case of syntax error in macro expansion, the expansion code can decide to stop processing anything. In that case, the token stream is malformed. This makes downstream users, like derive macros, ICE.

In this case, this PR manually cleans up the token stream by closing all currently open delimiters.
