Subject: [PATCH] Fixed bug: the execution is no more skipped after a failed
 build

After a failed build, further executions of the plugin were skipped, because
the MD5-summs suggested, that nothing is to do because nothing has changed.
Because of that, the MD5-summs are now removed in case of a failure.
