Clang: Avoid waiting plugin side if (re)parse fails

Browse Source 
If a parse or reparse operation fails, the corresponding translation
unit is "not intact" anymore and further job requests for that
translation unit will be silently discarded without notifying the
plugin. This is especially problematic when the plugin expects/waits
(for) a certain message.

A parse/reparse can fail due to e.g. an invalid commandline or an
internal crash.

In such a case, ensure to send some dummy results.
